This is a basic mod that adds smelting recipe to craft Leather from Rotten Flesh and conversely. I made this mod because I found it very useful and the others mods like this are not maintained updated at the latest version of Forge/Minecraft.
I just uploaded a version for 1.8 (think I'm the first who did this). The 1.8 forge installer can be found here: http://files.minecraftforge.net/minecraftforge//1.8 . The older mod versions can be found in the "View all downloads" section. Thanks for supporting me! Happy 2015!
Not too basic of a mod at all. I dislike it when you look for a specific mod such as this and find one but to utilise it you have to either get bundled with a load of features and other recipes you didn't want or you have to craft an item to mine an item to smelt an item that can be used to create an item that will be used to make another item that you can use to make one item from the recipe you want o.o.
