Crushed nuts are small pieces of nuts that have been broken down into finer bits, often used in cooking and baking. Common types of nuts that can be crushed include almonds, walnuts, pecans, and hazelnuts. They add texture and flavor to various dishes, such as desserts, salads, and granola. Crushed nuts can be made using a food processor, mortar and pestle, or simply by placing them in a plastic bag and using a rolling pin. They are often used as a topping for ice cream, yogurt, or oatmeal, enhancing both the taste and nutritional value of meals.
