Here's some food ideas:
Rat Kebob
2 Rats
1 Branch
Made with Cooking Fire
Rat Stew
3 Rats
1 Carrot
1 Apple
Made with Cauldron
Beef Stew
2 Cow Meat
1 Carrot
1 Onion (If/when we get onions)
Made with Cauldron
Roast Chicken
1 Chicken Leg
Made with Cooking Fire
For the rats you'd just have to right click and pick them up. Live rats are a hearty meal. For the chicken, I think it would be great, especially because chickens are currently just annoying. If they yielded some sort of meat, I believe many people would be very happy. Personally, I think the ideal goods from a chicken would be something like 1 chicken meat, 1 intestines, 1-2 feathers, and 1 bone material. The feathers would be used to make, for example, a quill to go with the parchment and make actual books or something.
Anyways, those're some ideas off the top of my head. Feel free to add more food ideas to my post, or completely ignore me, whatever works for you. >_>;;
