To prepare a strawberry and raspberry fool recipe, you will first need to prepare the fruit. Cut the strawberries in half and remove the pits. Peel and slice the raspberries. Place the sliced strawberries, ricotta cheese, sugar, and lemon juice in the bowl of an electric mixer and mix until the ingredients are well combined. Pour the mixture into the prepared baking dish and bake for 30 minutes at 325 degrees F. Remove the cake from the oven and let it cool for 10 minutes. Serve the raspberry and strawberry fool with vanilla ice cream.
