Sous vide legumes?
The good news is that sous vide processed dried beans are really great. There is absolutely no breakage because there is no friction in the bag. There is no need to stir, and there is no pan for them to stick to the bottom of. That's the good news. The bad news is that sous vide processing dried beans of any kind takes a long, long time. I do not insist that the beans must be cooked via sous vide. The beans can be cooked in a pot according to the directions on the packaging. The beans are available in cans already cooked, and there is no shame in that. I do it myself sometimes--however you cook them, drain them and save 1 cup of the liquid to go in the ragu. If you still want to try your hand at using sous vide to process dried legumes, here is how I do it:Procedure:

"Roasting" the peppers
Roasting is a misnomer. If you have never roasted peppers before, or you always hated it, click HERE for a detailed tutorial. If you are confident in your skills and method, roast and peel the green and red bell pepper and proceed.Make the Ragu
Make sure the bath is still set at 183 F/84 C. Submerge the packages of short ribs in the sous vide bath for two minutes. This will fully melt the gel. Cut open the bags, remove the short ribs and pat dry. Because of the advance searing procedure, there will be very little juice in the bag. Chop the peppers and the celery into "bean sized" pieces. Use a Ziploc gallon freezer bag to combine the short ribs, peppers, celery, beans with one cup of the cooking liquid, the tomato paste, garlic, and oregano. Add the salt and pepper to the bag and then lower it into the bath. It will slowly sink. Drape the opening over the edge of the sous vide container and secure with the lid. Remember to taste for accuracy later. Process sous vide for at least 2 hours at 183 F/84 C
