Who doesn’t love s’mores? Campfire-toasted marshmallows, milk chocolate, and crispy graham crackers make a delightfully messy treat. This recipe draws on the classic campfire treat, but refines it with a rich chocolate custard, vanilla bean marshmallow créme, and browned butter graham cracker crust. We've decorated this version in honor of the number pi, but you can adorn your pie in any way you choose.

This pie uses a few techniques and ingredients that may be unfamiliar to you. We have chosen each method to maximize flavor and help you create a perfect, lump-free pie. For example, cooking the custard in a water bath guarantees that your eggs won’t curdle. Less than ten grams of flavorless thickeners replace almost a quarter pound of cornstarch, allowing the rich flavor of bittersweet chocolate to sing. These techniques come from modern food science innovation and are completely safe. They may seem difficult at first, but they can make some forms of cooking easier and more delicious when mastered. Besides, what better way to celebrate the number pi than by benefiting from some of the innovations that science has brought into the kitchen!

Very cute. I used the tracing technique to hide "easter eggs" in the frosting of our Portal Cake last year.
That's a great idea!
