The Brits call fruit-and-cream desserts "fools," but we think of this tasty three-ingredient variation as a wise way to whip up an indulgent dessert with yogurt.
Whisk cream to soft peaks in a large bowl. Fold in yogurt. Spoon jam evenly on top and gently swirl in, leaving streaks. Divide mixture evenly among 4 glasses. Refrigerate for at least 1 hour or, covered, for up to 1 day before serving.
