Key Lime Parfait

I had never seen a key lime when I was growing up; I thought the juice was something that just came in bottles. Once I discovered the real fruit, though, I wanted to do something with it. So here’s a fresh, brightly flavored version of key lime pie, with a crisp graham cracker sablé standing in for the usual soggy crust. The sauce would also be great over sliced fresh apricots or nectarines. A scale is a must for making this dessert. And you’ll need ten 2 x 2-inch ring molds.
