I recently tried putting together a new modpack (for 1.16.3) without JEI, instead relying on Minecraft's now built-in recipe book. Unfortunately, I found out that Simple farming does not support this yet.

I'm not very familiar with the necessary mechanics but some kind of unlock criterium would have to be defined; for most recipes, obtaining one of the ingredients would probably be fine.

This would also be required before the mod can be used together with the gamerule doLimitedCrafting.

Love the mod, though! Keep up the good work!
