CustomItems & Minetweaker. Lets you make your own foods, change stack sizes, make your own items for recipes. I don't think it yet has the ability to change existing foods, but with some effort between mob properties & minetweaker, you could change the food drops of animals and the cooking recipes.Alright, is there a mod that lets you customize food yet?
As in:
1. Wheat turns to bread at a 1 to 1 rate -- so that wheat used for bread gives more food than steak.
2. Wheat can be ground into flour, and the flour turned into bread -- so that you really get more food this way.
3. Food stack sizes can be limited -- so bread and steak can be limited to 8 per, making the smaller stack size enough of an issue to make a stack of steak significantly better than a stack of bread (going on the assumption of the normal 27 inventory stacks and inventory space has value)
4. Sandwiches -- fish or steak -- can be created to give even more nutrition per stack, but not more total (i.e. -- a bread, plus a steak, would give more nutrition than a steak sandwich, but the sandwich stack has more total value) -- again, relying on small stack sizes to make a factor.
The idea here is to try to bring some better balance and value to vanilla foods, without having to resort to hunger overhaul / pams harvestcraft excess.
Also, this would return a role to mushrooms and mushroom stew -- which went from being the best food (at a cost of at least one extra inventory slot) to not worth the trouble when it got nerfed. (Specifically: the role of excessive total food, at stack sizes of 64).
Hunger Overhaul has a config option to change stack sizes based on saturation for all foods.
People seem to have this major misconception about hunger overhaul. It works fine without Pams (a mod I hate myself, way too bloated), and lots of stuff can be disabled/changed via configs.
Enviromine has a config system so you can change the properties of every block in game. If you want one to be more supportive or not fall at all, you can do that. Personally when I was playing around with the Physics sides of things I found the default settings way too fragile and make everything "stronger". (for example, just poking a ceiling in the Nether lead to a massive cave in, not good considering the mobs there and the design of the place)....I'm talking about Enviromine and how there's nothing that can act as support beams...
After a while, I just gave up with that part of the mod, in a big modded environment, it's a major headache.
