Baking is a piece of cake when you’ve got help at hand. Napa chef and mom Maria Helm Sinskey knows what to serve. Strawberry Custard Tart Ingredients 1 sheet all-butter frozen puff pastry (thawed), 10 by 13 inches 1 c. creme fraiche 2 eggs ¼ c. sugar 1 tbsp. plain flour ½ tsp. salt ½ tsp. vanilla extract 3 c. strawberries 1. On a lightly floured work surface, roll out pastry into a 12-inch round. Using pin, lay dough over a 10-inch tart pan with removable base, pressing it against the bottom and sides. 2. Chill dough-lined pan in refrigerator for twenty minutes. Preheat oven to 400°. 3. Prick the tart shell all over with a fork, then line with aluminum foil, allowing it to overhang the edges (to prevent burning). Fill with pie weights or dried beans. Bake shell for 15 minutes, then remove weights and foil and continue to bake until pastry is golden (approximately ten minutes). 4. In a bowl, whisk together the creme fraiche, eggs, sugar, flour, salt, and vanilla until smooth. 5. Remove tart shell from oven; reduce heat to 350°. Let the shell cool, then pour in the creme fraiche mixture. Return it to the oven and bake until custard is set (about twenty minutes). 6. Cool on a wire rack, remove from pan, and place onto a serving plate. Mound the berries on top and serve. How berry delicious.
