Sous Vide: Recipes, Techniques & Equipment (Part 7)

Anyone have a pork normande SV recipe or experience (pork with apples, cider, cream)?

My instinct is to cook the cubed shoulder pork somthing like 12 hours at 60C in the hard cider, then finish with cream, apples, vegetable garnish etc

Its not confit - it needs to be meltingly tender but retain some structure

This all depends on the final texture you want. We do pork shoulder for up to 48 hours at 60C. You get different texture at 24, 48 and 72 hours. We also like it at 65C for 36 hours, or pressure cooked for one hour. Each is very different result.

I think you will find that the fatty portions are not quite tender enough if you do only 12 hours.

Given your description I would guess 24 to 48 hours at 60C is your best bet.

Quick Q: anyone ever SV banana leaf for an extended period of time? Wondering if it will go bitter like aromatics.

I've done things wrapped in banana leaf - like a yucatan style pork shoulder, rubbed with achiote and lime, wrapped in a banana leaf and cooked at either 155F for 24 hours, 176 for 12 hours, or 182 for 8 hours... the banana leaf didn't impart that much flavor at 155, but it imparted a lot of aromatics at both 176 and 182... neither of them were bitter, although we didn't actually eat the banana leaf (does anyone actually do that?)

When I want the the shoulder to be tender but still retain some structure in "chunks" I can carve on the plate. I go 65 for 36 hours, good luck and I'd like to hear about the outcome! Are you going to burn off the alcohol from the hard cider before the vacuum?

The shoulder is cubed before cooking. Maybe brined.The skin crisped and puffed seperately

I ws going to seal it with some apple juice, apple brandy (not burnt off - only a small glassful), some cider vinegar, softened onions, bay leaf and seasoning.

After cooking, reduce the bag juice and finish with creme fraiche and caramelised apple slices.

I think red cabbage, rice or mashed potato might go well,

Is the alcohol in the best place?

Might it not be better to leave it out of the sv bag and perhaps flambée the meat (or maybe simply (rustically?) fortify the sauce) before service?

One of the appealing (to me anyway) concepts of sv is the possibility of accurate 'prototyping' or 'test driving' - making a single portion of a recipe to test the idea (or perhaps a few single portions with variations, for example to compare different durations) - before making a large quantity for any sort of 'event'.

This approach is surely particularly apt with materials like cubed pork ... isn't it?

It mainly requires enough time (just simmering time, rather than man-hours) before the event, rather than any other resources.

That is a REALLY good point - SV does not rely on size effects, so you can test drive a small portion and it will work well. Indeed that is how we test things for the book - we do multiple pieces and then cook them for various times. When we like a time-temp combintaion we do a larger sample to be sure.

I just recently cooked and wrote about a sous vide pork shoulder I did here. I found out that arount 70C for about 20-22 hours worked great for my purpose and it is similar to what you are looking for. It sliced great and crisped nicely but was also tender and unctuous.

Some time ago I cut a pork shoulder in three parts, bagged them with marinade (9 days at 1°C) and cooked them SV at 55°C for 24h / 48h / 72h, post-searing in almost smoking-hot rice-bran-oil.

72h was fork-tender, succulent and almost falling apart, but in its lean parts a bit dry.

24h and 48h were tender, succulent and juicy, but not perfectly fork-tender.

In all three cases the fat was perfectly soft, there was a nice crust, and the interior was pink after some contact with air.

I'm looking to SV pork spare ribs with dry rub as a means of shortening the time in the smoker.

My intention is SV beforehand for however long, freeze, then on day of serving thaw and stick in the smoker for hour or so at higher than normal(220-250) smoking temps,

eg 300 to get them colored fast and fat rendered for taste.

I know the rub should be reduced a bit, any suggestions for temps and time ?

Don't want to do 812hours cooks though.

Actually, I've just read Douglas's site and have a starting point, although his method is intended for complete cook.

For pork, you could brine for a day, then do 131-135 Fahrenheit for 6-8 hours to get the collagenase to do its duty on the meat and get it medium rare. It'll still be tough and none of the fat will have rendered. You intend to finish the cooking in the smoker, right?

Yes, spare ribs are normally 4 hours or so at 235 in the smoker,

wanna be able to reduce that to 90 mins or so and get the color/smoke flavor in

Smoking them first and then finishing on a grill works really well, btw. I've done it a few times now and the results are excellent: some char, rendered fat, and meat just the way you like it (whatever that means).

Wanted to report on a few vegetable projects following Keller's Under Pressure 85C advice.

Pumpkin fans should take note that SV is, far and away, the best way to prepare this finicky squash. I put ~3/4" cleaned, skin-on pieces into a bag with nothing else, and after 60m they were tender and bright, bright orange. After testing it out of the freezer, I'm planning to do several more so that we have a store of pumpkin for the fall.

Also at 85C, I SVed small red potatoes with rosemary, pepper, and smoked salt for 90m and finished them on the grill for some smoke and char. I think 120m would have been a better time if I wasn't finishing on the grill, as they were a bit too toothy out of the bag.

One note about these potatoes: they were somewhat grey and splotchy out of the bag. I'm not sure if they were that way in the bag or if something happened when they hit the air. Anyone got an opinion?

Sounds like what happens when potatoes oxidise. You could try adding some acid to the bag which should give a similar effect to putting it in acidulated water.

I intentionally avoided acid in the bag for flavor reasons, trying to replicate a roasted potato dish we have here often. I wish I had been more attentive and knew whether they were blotchy in the bag or immediately after the cut faces being exposed to the air. I also wonder how deep the blotches go....

I agree with Chris A. Smoke them first. They only need 10 to 20 minutes in the smoker. I would do that at a lower temp than 235 F if you can. Then bag them. The earlier in the cooking process that the smoke is introduced, the better in my experience. Smoking after the meat is cooked doesn't seem to work as well.

!0 minutes in the smoker before sous-vide should be adequate. The smoke flavor is then locked in the bag during cooking and penetrates nicely.

Use the search button at the bottom of the page to look for 'ribs'. I posted the temperature/time that I used for some killer baby back ribs that came out smoky and tender.

Does iodine limit oxidation?

ETA: It was Hawaiian pink salt, btw, not iodized.

OK, if you've eliminated that, then its out already.

Blackening of starch is a very sensitive test for dissolved iodine.

If that were somehow being liberated (even to a truly tiny extent), there would be the possibility of trying to eliminate it by using non-iodised salt.

But you are already!

Do you have a sample of this batch of potatoes to test (for comparison) by conventional cooking? That way you might see whether the unconventional cooking method had contributed to this artifact, or whether it was due to something in the potatoes, like their (pre-purchase) storage and handling conditions.

I have no more of them, but they were bought at a farm and I had prepared several other batches without SV that didn't produce these effects. Still, way to many variables to conclude anything.

I haven't noticed it posted here yet, but y'all should have a look at the excellent article in today's NYTimes on "Modernist Cuisine":

www.nytimes.com/2010/09/22/dining/22cookbook.html?_r=1&ref=dining

I hope I live close enough to regularly visit someone who can afford to buy Nathan's obviously amazing work.

Has there been previous discussion of the possibility of digital/DVD/etc. or online access to it?

Cheers, Mark

Looks like KitchenAid is making a foray into the market for sous vide equipment with a system called Chef Touch. It has a chamber vacuum unit, a freezer/chiller unit, and a steam oven unit - but oddly no water bath - all stacked together in a stainless steel tower.

Here's a YouTube video. I imagine the system is only avaliable in Europe, and no doubt shockingly expensive.

Pork normande results.

36 hours at 60C was definately too long or too hot, giving the pork shoulder cubes a fuzzy blotting paper texture.

24 hours at 58C is about the upper limit, for melt in the mouth texture.

If you are planning on re-heating I would scale that back to 18 or even 12 hours

I don’t know anything about steam ovens, but does the use of steam imply that they’re cooking at the boiling temperature of water? Also, wouldn’t a steam oven have far less heat conductivity than a water bath?

Presumably the steam oven works just like a combi-oven, right? That's what a lot of professionals doing large quantities of SV are using these days. I don't see why you'd want or need a water bath if you had one.

Has anyone tried he Kenwood cooking chef http://www.kenwoodworld.com/en/CookingChef/Home/ which builds an induction cooker into a mixer, albeit at a high price?

The web stite states temperature control in +/- 5C, with a precision on 2C, and this for a stirred system. It seems to me that the manufactureres are missing a trick here. At the high price they charge it surely could not have been that expensive to add a more precise PID temperature control...

      I got to thinking after the disgusting job of separating globs of fat from sous vide short ribs and debating never doing them that way again. If the fat renders out in a braise, but not in the sous vide, what temperature would you need to turn the fat liquid to get rid of it? Is it below well-done or do you really have to cook the shit out of it? Is it just temperature or a time&temperature thing?
       
      Along those lines, what happens with marbled, tender cuts? where is the sweet spot between solid fat and something more palatable?
    • By Daily Gullet Staff
      By John Sconzo

      The Daily Gullet is proud to present this, the first in a multi-part, front-row report on the recent "Spain and the World Table" conference. Watch for subsequent installments in this topic.

      In his introduction of Ferran Adria, Thomas Keller -- perhaps the most celebrated American chef ever -- described four elements that go into making a great chef. The chef must be aware. Once aware of one’s culinary and other surroundings that chef can then be inspired, which leads to the ability to interpret those surroundings. But a great chef does not stop there. Instead, the great chef continues to evolve. Ferran Adria, perhaps more than any other chef who has ever lived, is the embodiment of those four elements.

      The moment that Ferran Adria strode towards Thomas Keller on the stage at the CIA/Greystone’s World of Flavors’ “Spain and the World Table” Conference was electric -- as if a giant Van de Graf generator had been turned on. The feeling didn’t subside when Adria took the stage from Keller; it only became more pronounced as the packed crowd rose to its feet, raining applause, admiration and love on the Spanish master. Adria accepted the response with aplomb, and gave it right back to the audience -- and to his fellow Spanish cocineros, who were standing off to the side. He brought each one up to join him on the stage for a rousing thank-you to the conference organizers, sponsors and participants. Once this emotional release subsided, Adria got down to what everyone had been waiting for -- his discussion and demonstration.

      Ferran Adria, with eyes sparkling like the finest cava, began speaking Spanish in a voice as gravelly as the beaches of the Costa Brava, while Conference Chairman Jose Andres translated. The crowd, hushed and straining for every word, moved forward in their seats as Adria explained El Bulli and himself, with a lesson in recent culinary history thrown in. Ferran explained that El Bulli is not a business. While offshoots of El Bulli are operated on a for-profit basis, the restaurant runs without profit as a primary motivation. For example, he said, the greatest difficulty they have is distributing reservations. Given the extraordinary demand and the severely limited supply, he explained that they could simply raise the price of a meal to the point where the supply and demand met. Indeed, the price of a meal at El Bulli is in itself quite reasonable given the stature of the restaurant and well within means of most motivated diners should they be able to get there, and this is how Adria prefers it. He stated that he was not interested in cooking solely for those with the most money. He prefers to work for people with a true interest in exploring the limits of cooking with him. To this end he showed a short film depicting “A Day in the Life . . .” of El Bulli set to the Beatles’ song of the same name. The film showed a couple’s response to the experience.

      Ferran’s voyage into creativity began with a visit to Jacques Maxima at Le Chanticleer Restaurant in Nice, France. He learned from Maxima that to be creative is not to copy. This idea changed his entire approach to cooking -- from making classic cuisine to making his own. Aware of elaborate books of French cuisine, Adria resolved to catalogue his work, the results of which are the richly detailed El Bulli books, published by period. These books, as wonderful as they are, are huge and extremely expensive. During his presentation, Adria announced -- and demonstrated -- that the individual dishes photographed and described in a chronology within each book are all now available online at elbulli.com.

      He finished the philosophical discussion by talking about the general style of haute cuisine that he and others are engaged in. While others have coined the term “molecular gastronomy” to highlight the scientific component of the creativity involved, Adria rejected it, saying that all cooking is molecular: most of his techniques are in fact rather simple and don’t employ radical new technology. Most of the technology that they do use has been around for some time; they have simply adapted it to their own purposes. Nevertheless, he applauds contributions to gastronomy from Harold McGee and other food scientists, and welcomes their collaboration in the kitchen. He has yet to find a term that describes the movement: as of now, he feels that there really is no good name for this style of cooking.

      More than any other single thing, Ferran Adria is known for the use of “foams” in cooking. While he is proud of his achievements with foams, he stressed that while appropriate in some circumstances, the real utility of foams is limited. He bemoans their ubiquity -- and wishes to not be blamed for others’ poor deployment of the concept. In the course of describing this and other techniques, Adria made a point of stating that using them should not be inferred as copying. Techniques and concepts are to be used and shared. He invited everyone to learn and harness whatever they found interesting, and to employ it in to their own pursuits.

      Another set of techniques discussed and demonstrated by the master and his assistant, Rafa Morales from Hacienda Benazuza, included three types of spherification. These included the use of calcium chloride (CaCl) and sodium alginate as well as the converse, and exploration of a new agent, gluconodeltalactone. The original combinations of alginate into CaCl for “caviar” production, and CaCl into alginate for larger “spheres” have chemistry-related limits as to what can be sphericized. In private correspondence, Harold McGee explained to me that Adria described encapsulating a mussel in its own juice. While this would make the dish technically an aspic, unlike conventional aspics it remains a liquid. Adria said that though gluconodeltalactone is very new, and they are just beginning to get a handle on it, he is very excited by it. He also demonstrated a machine for spherification on a larger scale than they had originally been able to do, as well as liquid nitrogen and freeze-drying (lyophilization) techniques. At the conclusion of his demonstration -- and thus the Conference -- the audience once again awarded him a standing ovation.

      While Adria’s appearance was the culmination of the conference, the energy it produced was not just because of his stature in the world of gastronomy -- it was also due to the excitement generated by the conference that preceded it. If there had previously been any doubt, Thomas Keller’s welcome of Adria was a clarion: Spanish cuisine has landed on North American shores and is finding a niche in the North American psyche. Spanish cuisine -- in its multifaceted, delicious entirety -- lives here, too.

      With Modernist Cuisine I waited a couple of years and ended up with a copy from the 6th printing run the advantage of this was that all errors picked up in the erratta had been corrected in the print copy.  I am looking to get modernist bread soon and wondered if someone had purchased it recently to check or if someone knew of hand if they have printed any additional corrected runs
