Two outputs from a standard crafting table 1.15.2?

[Bluedragonflyer]

I am trying to add a crafting recipe to my mod that is a knife and an apple to get out 2 apple slices and the knife back but I don't know how to get the knife as well.

define "isn't working",
and show what you tried

“getContainerItem” keeps saying that it is unused

I have tried
@Override

public Container getContainerItem(){

return getContainerItem()

}

you return the actual method in the method that does not work
and is there a reason why you are not using the code feature?
