Cheese is a difficult-to-acquire ingredient, and it is also edible. Cheese can originally be made to mini pizza before it was removed in an unknown update. It requires 27 iron ingots spent on a bucket, a cow and a crafting table to make just 3 of these cheesy food.
It is more easily obtained if you have a lot of cows nearby. However, it is not recommended to rely on it as a food source as it requires a ridiculous 9 buckets to craft, though the buckets are refunded after crafting. Additionally, it only restores with an average saturation of 2.
