Vanilla Semifreddo with Rhubarb Compote

In Italy, there are many variations of semifreddo, which, literally translated, means “partially frozen.” Sometimes a semifreddo is made from sponge cake layered with slightly frozen cream; other times it’s cake-free, simply a lighter version of ice cream. At Lucques, we make this semifreddo from an uncooked “custard” base that has beaten egg whites (to make it buoyant and light) and whipped cream (to prevent it from freezing completely) folded into it. The result is a creamy frozen dessert that doesn’t require an ice cream maker or a true custard cooked at the stovetop. Strawberry and rhubarb are a classic combination, but though it’s tempting to temper the sourness of the rhubarb with sweet strawberries, I prefer the intense mouth-puckering quality of rhubarb on its own. This is a great party dessert since you can prepare all the components ahead of time.
