Was finally able to try out a cooking class with The Baking Education Center at King Arthur Flour in Norwich, Vermont. Gesine Bullock-Prado demonstrated how to construct a puzzle cake.
Gesine is demonstrating the trickiest part....cutting out a triangular wedge which will then be placed back into the cake. You need to invert the cake, reverse the crater you created and place the wedge back in the cake. Hard to describe. You need to see it.
The result is very impressive. A very fun class. Can't wait to try it at home!!!
