Hey guys,
I just found this on the official forum. It's a list of things that can be manufactured with the Refrigeratory. I don't have the refrigeratory myself yet, so unfortunately I can't give the breakdown of what is needed.
In addition the refrigeratory has 10 slots for storing food. I've already added that in the comment field of the refrigeratory.
If anyone has the formulas, maybe he/she can add these to the manufactures?
