You may have noticed that pesto sauce is somehow four times as expensive as tomato sauce. But sometimes, it’s just what you crave so you’re stuck buying tiny jars for six dollars that barely cover one batch of spaghetti. You can save money by making your pesto at home, and your blender is the perfect tool to help you do it. The raw ingredients are actually quite affordable and a little will go a long way in having you make several batches. Try blending these ingredients in your blender: 1/3 cup raw pine nuts, two cups of basil leaves, ¼ cup parmesan cheese, one tablespoon of lemon juice, two cloves of garlic, ½ a cup of extra-virgin olive oil, salt and pepper to taste. You can leave out the cheese for a vegan variety.
