I need some advice. I have one last piece of pork belly confit in the fridge. I brined these bad boys for about 5 days (brine included pink curing salt), vacuum sealed the squares of pork belly with lard and sous vide them at 158 F for 16 hours. I cooked this on 11/10/16 and its been in my refrigerator since.
Here is the general recipe I followed, with some modifications based on my taste: https://www.chefsteps.com/activities/...
The last piece is still vacuum sealed and submerged (mostly) in lard. Any visible pork only has contact with the bag.
It's staring at me. And calling my name.
I want to deep fry this sucker and have a little date night with the handsome devil I see in the mirror every morning, but the last thing I want is spoiled food. I can't find any conclusive information about how long pork confit lasts for. I've only seen references that duck confit or in general that the confit technique will last for months in the fridge. I have found no sources which directly addresses pork confit.
Questions/Factors I'm Considering:
- Does pork confit keep for as long as duck confit?
- Does vacuum sealing have any effect on the length of preservation?
- Does sous-vide cooking method affect the length of preservation?
I know I am probably being a bit paranoid, but I thought I would do my due diligence before taking the plunge, so to speak. Any advice on these questions would be extremely helpful and appreciated!
PS - you should totally make this if you are into sous vide, confit, food, or have any respect for the enjoyment of life. Flash-searing these things after cooking was OUT OF THIS WORLD.
Host's note: this delicious topic is continued from What Are You Cooking Sous Vide Today? (Part 2)
Duck breast, 57C for 90 min, pre and post sous-vide sear.
So the texture was not significantly different from what I get with my usual technique, which is grilling over charcoal. But it's more uniformly pink, and there are no slightly overdone spots. I am pleased with the results even though searing in the house means a ton of smoke and duck fat everywhere! (I did it on the stove in a cast iron skillet, next time I will place the skillet in the oven)

Welcome to the index for the Sous Vide: Recipes, Techniques, & Equipment topic, one of the largest and most influential topics on eG Forums. (The topic has been closed to keep the index stable and reliable; you can find another general SV discussion topic here.) This index is intended to help you navigate the thousands of posts and discussions to make this rich resource more useful and accessible.
In order to understand sous vide cooking, it's best to clear up some misconceptions and explain some basics. Sous vide cooking involves vacuum-sealing food in a plastic bag and cooking it in a water bath at precise temperatures. Though it translates literally as "under vacuum," "Sous vide" is often taken to mean "under pressure," which is a misnomer; not all SV cooking involves food cooked in conditions that exceed atmospheric pressure. (See below.) In addition, calculations for SV cooking involve not only time and temperature but also thickness. Finally, due to the anaerobic conditions inside the bag and the low temperatures used, food safety issues are paramount.
You can read the basics of SV cooking and equipment here. In the summer of 2005, Nathan Myhrvold (Society member nathanm) posted this informative, "I'm now going to answer my own initial questions" post, which addresses just about everything up to that point. For what came next, read on -- and be sure to order Nathan Myhrvold's highly anticipated Modernist Cuisine book, due in spring 2011.
As with all indexes of on-going discussions, this one has limitations. We've done our best to create a user-friendly taxonomy emphasizing the categories that have come up repeatedly. In addition, the science, technology, and recipes changed over time, and opinions varied greatly, so be sure to read updated information whenever possible.
Therefore, we strongly encourage you to keep these issues in mind when reading the topic, and particularly when considering controversial topics related to food safety, doneness, delta T cooking, and so on. Don't read a first post's definitive claim without reading down the topic, where you'll likely find discussion, if not heated debate or refutation, of that claim. Links go to the first post in a series that may be discontinuous, so be sure to scan a bit more to get the full discussion.
Recipes were chosen based solely on having a clear set of information, not on merit. Indeed, we've included several stated failures for reference. Where possible, recipes include temperature and time in the link label -- but remember that thickness is also a crucial variable in many SV preparations. (See below for more information on thickness.)
History, Philosophy & Value of SV/LTLT Cooking
Over the years, we've talked quite a bit about SV as a concept, starting with this discussion about how SV cooking got started. There have also been several people who asked, Why bother with SV in the first place? (See also this discussion.) What with all the electronics and plastic bags, we asked: Does SV food lack passion? Finally, there have been several discussions about the value of SV cooking in other eG Forums topics, such as the future of SV cooking, No More Sous Vide -- PLEASE!, is SV "real cooking," and what's the appeal of SV?
Those who embrace SV initially seek ideas about the best applications for their new equipment. Discussions have focused on what a first SV meal should be -- see also this discussion -- and on the items for which SV/LTLT cooking is best suited. There's much more along those lines here, here, and here.
Vacuums and Pressure in Sous Vide Cooking
As mentioned above, there has been great confusion about vacuums, pressure, and their role SV cooking. Here is a selection of discussion points on the subject, arranged chronologically; please note that later posts in a given discussion may refute earlier ones:
Do you need a vacuum for SV cooking, and, if so, why? What exactly is a "vacuum"? Click here, here, and ff. Are items in vacuum-sealed bags "under pressure"? Does a vacuum sealer create a vacuum inside the bag? Do you really need a vacuum, or can you use ZipLoc bags? Also see here, here, and here. If "sous vide" means "under pressure," aren't the items in the bag under pressure? There is more along these lines to be found in this discussion.
We've collected the most important of many charts in the SV topic here. Standing above the rest are Nathan Myhrvold's charts for cooking time versus thickness and desired core temperature. We worked with him to create these three reformatted protein tables, for beef, fish, and chicken & pork.
Nathan provides additional information on his charts here. Information on how to read these charts can be found in this post. For an explanation of "rest time" in Nathan's tables, click here.
Other Society members helped out as well. Douglas Baldwin references his heating time table for different geometric factors (slab/cylinder/sphere) here; the pdf itself can be found here. pounce created a post with all three tables as neatly formatted images. derekslager created two monospace font charts of Nathan's meat table and his fish table.
Camano Chef created a cumulative chart with information gathered from other sources including Thomas Keller's Ad Hoc. Douglas Baldwin shared this chart devoted to pasteurizing poultry. PedroG detailed heat loss and steady state energy consumption of sous vide cookers in these charts.
Finally, there is also an eG Forums topic on cooling rates that may be of interest.

Wikipedia defines pork wings as: a pork product made from the fibula of a pig's shank - a single bone surrounded by lean, tender meat.
Images from the internet look like a finger-size bit of meat around a bone.
Mine, however, look more like the meat (lots) which surrounds a bone. My butcher called this cut pork wings.
You can see on the right that there's a small amount of bone.
My butcher said he regularly ate SEVERAL of these. But this one measures 15 oz (425g).
He also said it had to be cooked slowly.
So, if I cook these sous vide, what temp and for how long?
