Do all of the new ingredients have uses yet? I'm using JEI and I don't see any uses for yeast yet. Also, is there a list of which new ingredients are craftable/renewable? Based on JEI I know that vinegar, yeast, and curry powder don't have recipes, but am I missing any others? This is a really cool mod, and if I recommend it to anyone for a server I'd like to know which ingredients are non-renewable and would run out in multiplayer so I could give people a head's up on that.

vinegar and yeast are made with the vinegar/yeast pot. Curry is currently a dungeon item until the necessary ingredients to make it are added in.
