It's good to have a combi oven to cook sous vide. We do a lot of 24 hour braises sous vide in combi ovens(biotherm settings for Altoshams). Anything from lamb shoulder to pork belly to oxtail to short ribs. Combi ovens offer very consistent temperatures to cook at for very consistent results. One of my favorites is making carrot puree sous vide. Just some carrots,honey,cardomom,butter,salt and pepper; cook until very tender in the bag(in a pot of water) and puree in a blender with a little cream.
