Trifle is layer upon sweet layer of fruit, cake and custard and the possible combinations are endless. Anna begins by making individual Lemon Blueberry Trifles. These are a perfect weeknight dessert. Then she moves on to the most famous of all trifles—the Classic English Trifle—with fresh berries and sponge cake. Anna finishes off with a grand Double Chocolate Pear Trifle. This is rich, decadent and sure to impress.
