This fluffy mix of whipped cream and pureed fruit is a classic English treat known as a fool. It is often served in a parfait glass, but it also makes a great topping for angel food cakes. If you’re feeling extra fancy, serve it over graham cracker crumbs in a wine glass and top it with whipped cream. Your guests will surely be impressed. **Plan ahead. The berry juice needs time to chill after mixing it with gelatin. Allow yourself a little over 3 hours for this step. This step can also be completed a day before you plan to serve the dessert.**
