IIngredient
In recipes, you often see IIngredient as input. The following things are IIngredient's:
ItemStack(f.e.item('minecraft:apple'))- ore dict (f.e.
ore('ingotIron')) - Or ingredient (f.e.
item('minecraft:apple') | item('minecraft:iron_ingot)) FluidStack(f.e.fluid('water'))GasStack(f.e.gas('oxygen')) (Mekanism required)
So any time you see IIngredient you can technically insert any of these. However, fluids and gases might not give the expected result. In crafting recipes they are turned into any item that contains that specific fluid liker buckets or tanks. In other recipes it might be turned into a bucket.
