This gooey bread pudding made with caramel-like dulce de leche from Latin America is so much more than the sum of its five parts. To add even more flavor, throw in a handful of fresh or frozen raspberries or blueberries before baking. Serve the crème anglaise as a sauce for fresh berries or poached fruit; spoon it over pound cake or chocolate cake; or use it as a base for making ice cream.
