I think it would be nice if there was alot of food items, and along with these food items, a mini-game where you literally cook the food, like drag and drop ingredients in a pot, stir/ change temperature etc., and maybe everything is like a quicktime event, like if you fail the food might have negative effects or just less pottent or something like that same thing with potion brewing or maybe a bit diferent if they know how to do it diferently, still i think it would be nice if there was such a mechanic in the game wouldn't you? EDIT: a good point would be that this cooking game could take a lot of time, unless it is made really simple yet fun, something that could help this situation would be that already known recipes can be made instaly(by skipping the game) but its potency/effects will be randomized, like RNG luck if you get my drift
I think it'll take too much time from the game, unless you get some sort of specialization in cooking. This way, interested players can make better food than average.
