The idea was lifted from this page. I should try making regular custard at some point as well. Sadly, because it takes an hour and a half to cook (and longer to set), I will be up until way too late. But it will be a voluptuous breakfast.
I made a few changes to the recipe (no bacon or onions, added spinach) because I have a vegetarian roommate. Tomorrow, I'll post about how it came out.
