In a small saucepan, sprinkle the gelatin over the cold water. Let it stand for 1 minute.
Heat over low heat, stirring constantly until the gelatin completely dissolves.
Remove from heat and allow the mixture to cool for 5 minutes.
Place the sour cream, sugar, lemon juice, almond extract, vanilla extract, 1 cup chopped cherries, and the gelatin mixture into a blender.
Blend until smooth and the cherries are fully pureed.
Transfer the mixture to a large mixing bowl.
In a separate bowl, whip the heavy cream until soft peaks form.
Reserve 1/2 cup whipped cream for serving.
Gently fold the remaining whipped cream into the cherry mixture.
Fold in the crushed amaretti cookies and the remaining chopped cherries.
Divide the Bing Cherry Amaretti Fool Recipe mixture evenly among 8 dessert dishes or glasses.
Refrigerate for at least 2 hours or until set.
Top with the reserved whipped cream and optional garnishes before serving.
