Ok this is probably really obvious but I'm trying to make a food that smelt's into a cooked version of it. Like porkchops, or chicken, or beef to steak etc; The code line GameRegistry.addSmelting want the output to be an itemstack, but I need the output to be a food, how do I do this?

new ItemStack(myFood)

Im a bit confused with this, can you explain it a bit and where should I put it?

Items are static objects that are used to define behavior of that item, and ItemStacks are the actual Item. When you look in your inventory, you're actually looking at ItemStack instances that have the data of the Item or Block that is passed to them. The addSmelting() method requires an ItemStack parameter as the output, so give it one that contains the data of the item you want to receive (new ItemStack(myFoodCooked)).

Thank you, that made sense and fixed it!
