Here's a delightful topping for yogurt, ice cream, or other desserts, or a sweet snack for eating out of hand. Walnuts are called for here, but you can swap them out with pecans, hazelnuts, almonds, and other types of nuts. You can also scale up the recipe to make a big batch for storing in an airtight container at room temperature, or for serving to a crowd at a cocktail party.
