Pairing lemon with other fruits in desserts is a great idea, as the bright, tart flavor of lemon really helps to highlight other flavors. Bea, from la Tartine Gourmande, used this strategy when making her luscious Blackberry Tartlets with Lemon Cream. The tarts are quite easy to make because the elements are made separately and combined before serving. The tart shells are made with pâte brisée and are prebaked, a step that you could easily do a day or in advance if you want to try the tarts during the holidays and need to save time. The lemon cream, which is really like a light and rich lemon-flavored custard, can also be done ahead of time. Before serving, the cream is spooned into the tarts and garnished with fresh berries. It looks like Bea gave some a sprinkle of confectioners' sugar and garnished others with small sprigs of mint.
Although she used blackberries in her tarts, Bea is quick to point out that you should use whatever type of fruit is seasonally available - strawberries, raspberries, etc. We're suspect that the tarts will taste just as good without any fruit topping, too.
