The Electric Grill menu doesn't list Pepper Bread or Mush Fry. (This is an existing grill in an existing save, I haven't tried building new ones.) It's a long-lasting colony where I've cooked a large amount of pepper bread in the past, so I've definitely discovered the ingredients (and I have both of the ingredients of the pepper bread in stock.)
Steps to Reproduce
Look at menu for Electric Grill.
