Hi, I made a small mod for more crafting and smelting recipes in a balanced way (the recipes aren't too OP). I recommend using NEI.
You can:
Craft: gunpowder, string from wool, bottle of enchanting, grass block, enchanted golden apple, saddle, all types of horse armor, nametag, elytra, totem of undying, obsidian
Blast: cobblestone - output stone, stone - output smooth stone, clay - output brick, netherrack - output nether brick, sand - output glass
Additionaly, you can turn rotten flesh into leather in furnace, smoker or on campfire.
You may use this mod in your modpack.
More updates coming soon! Please rate this mod so I can improve it and add more recipes
