Yeah, it's another data pack that adds recipes to the game. More specifically, it adds 77 of them (20 new crafting, 17 revised crafting, and 40 "uncrafting"). I put it together for my own use, and so figured, I might as well release it. It has recipes I like, and only recipes I like. If you like 'em too, feel free to use the pack. But if you like other recipes better, well, use a different data pack. ;)
The recipes all have unlocks for the recipe book, just as do vanilla recipes.
The included recipes are....
Chainmail Armor: Constructed from a combination of iron ingots and iron nuggets. A full suit of iron armor requires 24 ingots; a full suit of chainmail armor requires 15 ingots and 9 nuggets, just two-thirds as much iron. Recipes unlock as soon as you have an iron nugget in your inventory.
Cobweb: Made with string and a slime ball. Recipe unlocks as soon as you have string in your inventory.
Cocoa Beans: Made by combining a pumpkin, an ink sac, and a bucket of milk. (Yes, you get the empty bucket back.) I know it doesn't make a whole lot of sense, but I just get tired of never having access to brown dye until I happen to find a jungle. Recipe unlocks when you have a pumpkin in your inventory.
Elytra: Made with leather and phantom membranes. Recipe unlocks as soon as you have a phantom membrane in your inventory.
Grass: Made by combining dirt with grass or ferns. Recipe unlocks when you have dirt in your inventory.
Horse Armor: Constructed with a regular helmet, two chestplates, and two leggings of the appropriate type. Each recipe unlocks as soon as you have the appropriate base material (an iron ingot, a gold ingot, or a diamond) in your inventory.
Leather: You can now create leather by smelting rotten flesh. Recipe unlocks as soon as you have rotten flesh in your inventory.
Monster Spawner: Crafted with iron bars and a nether star. (When placed, a spawner will of course be a pig spawner; you'll need to be able to craft or find mob eggs in order to change the type. I'd suggest using "Rainbeau's Egg-Heads," my data pack that allows mobs to drop their heads and/or spawn eggs.) Recipe unlocks as soon as you have a nether star in your inventory.
Mycelium: Made by combining dirt with mushrooms. Recipe unlocks when you have dirt in your inventory.
Name Tag: Crafted with string, leather and paper. Recipe unlocks when you have paper in your inventory.
Nether Star: Crafted (for those who don't want the bother of actually killing a wither) from diamond blocks, wither skeleton skulls and soul sand. Recipe unlocks as soon as you have a wither skeleton skull in your inventory.
Orange Dye: Crafted from pumpkin seeds. Recipe unlocks when you have pumpkin seeds in your inventory.
Podzol: Made by combining dirt with dead bushes. Recipe unlocks when you have dirt in your inventory.
Saddle: Constructed with leather, wool, and iron ingots. Recipe unlocks when you have leather in your inventory.
Stairs: All stair recipes now give you six stairs for your six input blocks, instead of just four. These aren't new recipes; the vanilla stair recipes have been changed.
Stick: You can now turn saplings into sticks. Because, why not? Recipe unlocks as soon as you have a sapling of any variety in your inventory.
Uncraft Armor: Any piece of armor (either regular armor or horse armor) can be "uncrafted" to get back its components (leather, iron nuggets, iron ingots, gold ingots, or diamonds, as appropriate). Each recipe unlocks as soon as you have the relevant armor item in your inventory.
Uncraft Glass Panes: Eight glass panes of a given color can be "uncrafted" back into three glass blocks of that color. Each recipe unlocks as soon as you have a glass pane of the relevant color in your inventory.
