How did Mortimer buckle do his bread making class?

It seems like you're asking about a fictional character named Mortimer Buckle. I don't have access to specific information about fictional characters unless they come from a well-known story or book.

To help me figure out what you're looking for, could you please tell me:

* Where is Mortimer Buckle from? Is he from a book, a movie, a TV show, or a game?

* What kind of bread making class are you referring to?

Once you provide more context, I can try my best to answer your question!
