The Helpful Recipes mod adds multiple new recipes into the game that allows you to craft some uncraftable items and more ways to craft certain items.
Ever wanted to smelt your stacks of raw copper, gold, and iron blocks? Well, now you can!
Want to make some wooden stairs and slabs without getting ripped off? Just put them in the stone cutter! (Well I guess now it should be called a block cutter huh?)
You can see the full list of new recipes in the images!
