This mod is called Additional Recipes.

If you don't have the resources to craft the items that you need, or if you don't want to wait for your resources to accumulate, then this is the solution for you!

There are some items that don't have a recipe. You can add the items to the list, and then it will appear in your inventory.

You can edit the list of recipes and the ingredients.

If you don't want to wait for your resources to accumulate, you can craft the items yourself using the recipe.
