Is there a way to add custom Anvil recipes?

[Sirpwnsamin]

For my mod, I would like to have item1 + item2 = item3 in an Anvil, I searched online everywhere for an answer but only found a way to make an item repairable in an anvil.

 

Any help is appreciated

Anvils are for renaming and adding on a item. Not crafting, you have to a "custom anvil"
