Mini Tart Shells are trim pastry crusts commonly used as a base for sweet or savory tart fillings. It’s similar to a shortbread cookie recipe that’s made from a mixture of flour, butter, sugar, and egg yolks. The texture is crumbly which complements the filling. In this recipe, the shells are fully baked before adding the custard filling. This technique ensures a crisp and golden shell that holds up well to the moisture of the custard.
