Cheese Mod 1.4.0 is my first mod.
It adds four kinds of cheese: Normal Cheese, Hot Pepper Cheese, Moon Cheese, and Cream Cheese.
Normal cheese can be crafted using 5 buckets of milk, like this:
The other kinds of cheeses can be found in the other dimensions, as deposits in the rocks. 
Cream Cheese has a very complex recipe, and will not be described here.
COMPATIBILITY ISSUES
Cheese Mod 1.4.0 (for some reason) will not work with existing worlds. It will say something like:
Uh oh! It seems like a mod is breaking the ID map. Please revert to original mods.
Please do not use this mod with an existing world!! Make a new world instead.
Also, rainbows might not show up when other mods are loaded.
Note: Do not link to the project page, as the URL changes to include the latest version.
