Hello, does anybody know if perhaps there is a way for a crafting recipe to take no ingredients? Or maybe allow fuels(items with fuel property) to be automatically inserted into the furnace crafting slot?

To answer your first question, I just tried two different approaches of having no ingredients. The first one involved having an ingredient with count 0, which failed: Leaving the ingredients completely empty caused the game to freeze upon opening the crafting and inventory screen:
So this are two ways how not to do it. But you should wait until a modding expert gives his or her opinion about it.

Doesnt treefarm mod have a recipe that produces liquid air with no ingredient required? Look at their code

I don't know what you want to produce in your mod, but using an assembling machine with a supply of infinite water would also do the trick in case you want to "extract" stuff from the water.
However if you have a diffrent scenario in mind, this would make no sense.
