Today is the 371st anniversary of the signing. I celebrate every year with a Mazarin cake. I have no evidence that the Cardinal is associated with the cake, but it seems likely; and, besides, I can’t think of a more appropriate dessert to make. (Traditional Wespthalia foods like pumpernickel, ham, and blood sausage are not on the menu.)
I use the recipe here, modified by using a pre-made graham cracker crust instead of the shortbread crust it calls for. It’s a lot simpler, and it tastes a lot better. I also strongly recommend whipped cream on top.
