Toaster of Alchemy

Description
This toaster has a mysterious, opaque screen. Putting two objects in and turning it on will fuse both objects together in a way that usually does not involve cooking. Putting one food-related item will cook it normally.

Trivia

 * Someone thought of trying a can of cat food and a quantum physics textbook. The first time it yielded conceptual cat food, which Ellie ate happily, but the second time it just came out with a copy of Cooking for Your Cat by an author who doesn’t seem to exist.
