To prepare a after eight tiramisu recipe, first you need to prepare the ingredients. First, you'll need the following ingredients: 1 cup ricotta, 2 tablespoons granulated sugar, 1 teaspoon vanilla extract, and 1 tablespoon saffron flakes. Melt the butter over medium heat. Add the sugar and vanilla and stir until the mixture is completely melted. Remove the saucepan from the heat and add the milk. Simmer until thickened, about 15 minutes. Pour in the egg yolks and beat until frothy. Gradually stir in beaten egg whites until they're stiff peaks. Slowly pour the cooled mixture into the prepared ramekins. Cover with plastic wrap and refrigerate until firm, at least 1 hour. Serve with ice cream or whipped cream.
