I figured it out quite quickly - as others have said, tutorial would have been nice but it's fairly intuitive so I understand why you skipped it to save time.
Only thing that bugged me was sometimes I swear my clicks weren't registered; I think maybe a conflict with the recipe blur hover and clicking, but ingredients didn't always work either. So I'd have to go through my ingredients and figure out what didn't register.
Overall nice solid game, an I am pleased to say I managed to craft a delicious legendary biscuit
