Benefits of Dill Seeds
When you re cooking with fresh dill discard the stems use only the leaves and add them toward the end of cooking because heat diminishes dill's flavor. Mix dill weed with plain yogurt and use it as a dressing for carrots cucumbers or peas. Toss fresh dill with cooked potatoes and roasted vegetables. A pesto made with dill weed olive oil garlic walnuts and Parmesan cheese is a topping that you can use with fish and chicken.
