Cultured Key Lime Pie Frozen Yogurt

To make Cultured Key Lime Pie Frozen Yogurt, we blend together Key lime juice, biodynamic organic yogurt, buttermilk, and grass-grazed Ohio milk. Crumbled, from-scratch, extra-salty Salty Graham Gravel—a.k.a. the crumbled graham cracker pie crust—is folded in by hand before each batch goes into the freezer.
