Pasteurizing Eggs Sous Vide


Recommended Posts

I don't use jumbo eggs, myself, but I believe it wouldn't hurt to cook them longer than two hours.

 

The only anomaly I've run into with pasteurized eggs is that the yolk is somewhat more likely to break when the shell is cracked, compared with raw.  I don't see this as a real problem.  I manage to break the yolk of many a raw egg.

should you want to shorten the time for this :

 

consider placing the eggs in warm water that less than 130 for 'a bit' to take off the chill

 

however, I cant say what the total time might be.

 

if its important for health reasons that they be pasteurized, rather than extending refrigerator life

 

dont fiddle

 

remember   after you are done and dry them, the carton you keep them, if its the one that came with those eggs,  in is not in theory pasteurized 

 

should it be contaminated.

correct.


 


in the long run just put them in the bath as it heats up.


 


I use the CSB  as its right there, and Im only really interested in the yolks for sauce purposes most of the time.


 


if its really important, BB&B sells egg containers that you can clean w hot bleach etc :

probably cheaper plastic items at Target and Walmart etc

One more question, if you can answer. If you use a container like the one you show rotuts, cleaned with bleach etc, how sure it is that the eggs don't get contaminated again, after pasteurization? 

I'm planning to use the eggs for some frozen desserts and tiramisu, where I want to have another option beside pate a bombe and/or a hot meringue.

""  eggs don't get contaminated again, after pasteurization? ""

 

nothing is for sure

 

but most egg contamination is from Salmonella.  its unlikely to live in your refrigerator, etc

 

normal hand washing, routine cleaning would probably be enough,

 

of course, beware of recent eggs and their cartons and well, that chicken you just bought ....

Last night I pasteurized two eggs for hollandaise, but this time I pasteurized at 57 deg C, since I was cooking a steak at that temperature.  As previously reported the whites were indeed milky but the yolks were perfect for Hollandaise.  At least until I dropped one yolk down the drain.

 

Fortunately it is possible to prepare a superb hollandaise with but one yolk.

Sounds like much more work and mess to me.

 

 

If you're doing it for something you plan to use separated eggs in anyway, and you put the eggs in a baggie either way, it seems like it is just the order of mess making that changes, not the mess?

The difference is in one case you have pasteurized eggs slopped all over your counter.  In the other case you have unpasteurized eggs slopped all over your counter.

 

Also consider that eggs come in nifty little sealed containers.  If you break and separate the eggs first you have to deal with bagging the mess.  Compare a simple inexpensive sandwich bag to a vacuum bag.

 

But I may be too negative.  Try the experiment and report back.

If saving time is in an issue, you can just make the hollandaise sous-vide with plain eggs, and it will pasteurize while cooking. The cooking step takes about 30 minutes; at 65°C eggs will be pasteurized in about 10 mins. I haven't found any downsides to this approach.

Ive pasteurized eggs in the past in a water bath, lets say 130.1

 

Ive noticed that as the eggs warm up . there are tinny bubbles on the various surfaces.

 

the I rapidly chill and dray and refrigerate.

 

as the eggs cool in the cold water , Im betting its possible that water re-enters the egg.   I have not done the studies where I weight the egg etc

 

and figure this out.  Im not immune compromised  

 

if this indeed happens and an immune compromised host is where these eggs might go in the future :

 

consider a zip-bag  with water in it  ( whicch also becomes pasteurized ) the a cold ice bath with those eggs still sealed in that same bag

 

into cold water.  if water indeed seeps back into the egg  ( and I do think a little does )  it will come from the sealed bag w some pasteurized water

 

still in it.

Interesting thought. That would be another reason to perhaps separate the eggs first if making something that requires just yolks or whites, and pasturize in a small baggie rather than in the shell. That would be less effective for doing a bunch of eggs ahread of time to keep in the fridge, though.

I chill my pasteurized eggs in the ice bath still in their knotted sandwich bags.  I've kept them this way in the refrigerator for a couple weeks....or more.

here are some times and temps :

 

https://thatothercookingblog.com/2013/07/16/pasteurizing-eggs-or-mayo-at-home-sous-vide-134-6-f-for-2hr/

 

is it important to keep the yolks separate ? the only real advantage  is that is you only want to use one yolk and open the bag , in theory the remainder are no longer pasteurized.

Thank you Rotuts. I have a lot of yolks left over at work from one of my cakes. Finally I am coming out with a new product where I can use yolks and in decent quantities, so to eliminate waist. I am looking for the less painful  and economical way to pasteurize the yolk to use in a product that doesn't require cooking. So, my main objective is pasteurization. I am afraid though, for what I read on line, that I will need a permit to use sous vide, even if by just water displacement. I am going to ask on the pastry forum. Thanks!

Good Luck !

 

its wise to be on the safe side under those circumstances, with every detail.

 

business use and home use  might have little in common in the long run.

Bumping this up to get the group's opinion on how to accomplish something. Last year in NOLA, I treated myself to breakfast at Brennan's, which has two of my very favorite breakfast dishes in the world: egg yolk tartare and eggs hussarde. I was talking with the waiter about how they achieved the perfect texture for the egg yolks in the tartare dish; it's exactly what you get in the ideal over-easy or lightly poached egg. Perfectly runny. No solids at all. That good "done" taste and velvety texture that lets you know it's cooked enough. 

 

I'm thinking through how to accomplish this. The yolks tartare are not served whole; they're as if one just poured them out on the plate. I did not ask, and should have, whether they are cooked whole, or whether they're lightly beaten and then sous vided.

 

I'm thinking if I were to lightly beat the egg yolks, then pour them into a bag, and sous vide, I'd get the effect I want. What would be the time and temp y'all would suggest for this? I'll save the whites for another day.

 

The yolks tartare are pooled in a salad plate at Brennan's, with some grilled shrimp circling a tower of crispy fried sweet potato strands in the center. It's insufferably good.

Don't ask. Eat it.

      I really want to improve the flavor of my chicken breast so I want to try to inject brine with fat and flavors.
       
      I would like to try brining with some hydrocolloids. The one example I found is this: https://torontofoodlab.com/2013/08/20/meat-tenderizing-with-a-carrageenan-brine/.
       
      However I cannot apply that to my chicken breast because I am cooking it sous vide, so the chicken will not reach the temperature needed for the carrageenan to gel.
       
      I am thinking of using Methyl cellulose, first disperse in hot water, then leave it for 24 hours in the fridge, then add salt, fat and flavors and inject it.
      I am afraid that until it reaches the 50C or 60C that the Methyl cellulose needs in order to gel, the liquid will escape.
      Any ideas?
      Thanks.

      Thanks for putting up this forum 🙂
      I would like to bake using a combination of sous vide and a conventional oven. Would it be possible to put the dough in a vacuum bag cook it sous vide at 37C for the dough to raise optimal and then put it in a conventional oven?
      Thanks

      Warm Onion Bavarois
      * 300g Sweet Onion purée
      * 250g Whole milk
      * 150g Whipping cream
      * 150g Chicken stock (or fresh vegetable nage, not stock cubes)
      * 3.5g Gellan gum
      * Seasoning
      Lightly grease with vegetable oil the moulds you intend to use (darioles, ramekins etc) and set to one side.
      In a pan (but not on the heat), whisk together all the ingredients.
      Place on a medium heat and whisk continuously, the mix will start to thicken slightly. Carry on whisking for a further 3-4 minutes when it has started to bubble. Then quickly pour into the greased moulds & chill.
      To reheat for serving, just place the ramekin in a pan of water and simmer gently for 8-10 mins.

      I have been buying country style bone-in ribs instead of bone-in pork chops. I season them with a rub very similar to Emeril's Rustic Rub spice rub and use a heaping tablespoon a rendered Nueskie's Applewood smoked bacon fat in the Food Saver vacumn bag. We have been using 2 ribs in the bag but have made the decision to switch to one to split. The meat is so rich and flavorful that we can easily split one and enjoy the meal even more.
      For a sauce, I cobbled together a sauce made with the juice of half a valencia orange, the pulp from 1 passion fruit, 1 cup pitted cherries (I used rainiers and bings in this one), 1 tsp Dijon mustard, 1/2 cup white wine, juice from 1 lime, 2 tsp honey, garlic cloves crushed (I used roasted garlic that I keep in the fridge and 'crushed' them in my 'special' coffee grinder(2)) and 1 medium sized shallot. I used the same bacon fat to soften the shallots, then added the rest of the ingredients and let it reduce by about a third and then let it rest and reheated it when the pork ribs were done.
      I kept them in the sous vide at 141 from 10:00 AM until I got home from work at 7:00. It took another half hour +/- to change clothes, pour a glass of wine, reheat the sauce, make a salad, and heat up the garlic bread that I keep prepped in the freezer. After the bread was heated for about 8 minutes, I switched the oven to broil and took the bread out of the oven.
      I have started to experiment with using the broiler element to put color on the proteins that I have cooked in the sous vide. I have placed the oven rack on the third rack from the top, leave the door ajar while I bring the broiler element up to heat. I use my 10" stainless steel saute pan with a stainless steel rack in the pan for the protein. I open the sous vide package and pour the liquid that has accumulated in the bag into the bottom of the pan. I put the ribs, fattest side up on the rack and place the pan in the oven. I leave the door ajar and let them stay in there for 8 mnutes.
      That timing has worked extremely well for both the ribs and the chicken that I have done. I don't flip them yet and that hasn't been necessary for those 2 proteins. (I was much less successful with this formula for the flank steak which I think needs to be closer the heat source for less time).
      At any rate, the broiler is working well for color and the meat and sauce are great. The sauce also works very well with chicken. Haven't tried it yet with the salmon.
      Just wanted to share as I really love this sous vide thing and wanted to share.
      Sorry no photos yet. I haven't figured that part out yet but my husband promises to teach me.

      Utilization of meat leftovers from sous-vide cooking
      Sometimes when you buy a nice cut of meat, your eyes are bigger than your and your beloved's stomach. So what to do with the leftovers?
      In Tyrolia (Austria) they make a "Gröstl", in Solothurn (Switzerland) they make a "Gnusch", in the Seftigenamt (a region in the Swiss canton Berne) they make a "Gmüder", and we (Pedro and SWAMBO) make a varying concoct using ideas from all of the three. We call it "Gröstl", but it is not necessarily a typical Tyrolean Gröstl, and it is different each time, and we usually do not top it with a fried egg as they do in Austria.
      Ingredients

      All your meat leftovers
      Onion (compulsory)
      Any hard vegetable (we prefer celery stalks, or zucchini)
      Any salad (iceberg lettuce or endive/chicory or any other salad leaves, may contain carrot julienne)
      Fried potatoes, or alternatively sweetcorn kernels
      Sherry or wine or bouillon or the gravy you preserved from your last LTLT.cooked meat for simmering (I usually prefer Sherry)
      Eventually some cream (or crème fraîche)
      Salt, pepper, parsley, caraway seeds (typical for Tyrolean Gröstl), paprika, condiment (in Switzerland we use "Aromat" by Knorr, which contains sodium chloride, sodium glutamate, lactose, starch, yeast extract, vegetable fats, onions, spices, E552)'
      vegetable oil (I prefer olive oil)




      Mise en place

      cut your meat in small cubes or slices
      cut the onion(s) not too fine (place the first cut below your tongue to avoid tearing during cutting)
      cut the vegetables about 3-4 mm thick
      cut the salads to pieces smaller than 4 cm, distribute on the cutting board and season deliberately
      cut the potatoes to 1 cm cubes
      place 3 heavy skillets with ample oil on the stove

      Cooking

      in skillet 1, stir-fry the onions, add the hard vegetables still stir-frying, add salad, add sufficient liquid (Sherry or wine or bouillon or gravy) for simmering under a cover until soft. If desired, reduce heat and add some cream at the end.
      in skillet 2, stir-fry the potatoes until soft (in case of sweetcorn kernels, add to skillet 1 after stir-frying and use skillet 2 for skillet 3)
      in skillet 3, as soon as the vegetables and the potatoes are soft, sear the meat in just smoking oil for 30-60 seconds, then add to skillet 1

      Serving
      You may mix the potatoes with the vegetables and meat to make a rather typical Gröstl, or serve the fried potatoes separately; we prefer the latter, as the potatoes stay more crunchy.
      Do not forget to serve a glass of good dry red wine!
