Magic Microwave Lemon Curd

In From the Source, Season 3, Chef Katie Button makes a classic lemon curd to top Torrijas (a Spanish version of french toast!). While this lemon curd recipe isn’t the same as the show, Chef Katie Button uses this magic trick to make an EASY lemon curd at home. The method is borrowed from her mother, Liz Button. Liz owned a catering company when Katie was growing up, and has used this method for years with much success! It’s a good reason to have lemon curd around all the time!
If you’re looking for the recipe for Torrijas, it can be found in the Cúrate Cookbook here.
