I for one absolutely love how the cooking system becomes more complex the further in game you get, but i feel like there's a lot of room for even more food recipes. I know that mods like Darkness falls often add extra food items and whatnot, but for me, i see that just adding like 1 or 2 new food items to the game can suddenly open just a LOT of different opportunities.
One example would be something simple, processed cheese. Suddenly a whole new world opens up.
Cheese + Large Beef Ration + Cornbread = Cheeseburger
Cheese + Can of Pasta = Mac and Cheese
Cheese + Cornbread + Animal fat = Grilled Cheese
Cheese + Potato + Raw Meat = Loaded baked potato
Let's get even weirder.
Cheese + Beer + Large Chicken Ration + Cornmeal + Animal Fat = Nachos (because Beer cheese sauce)
Mac and Cheese + Peas + Canned Tuna = Tuna Casserole
Cheese + Chili Dog = Chili Cheese Dog
Now that i think about it, there potential for things not cheese related too!
Large Chicken Ration + Cornmeal + Animal Fat = Fried Chicken
I could keep going but i think i've made my point. I'd absolutely love to see what else you guys could come up with as well.
