I love the earthy aroma of red, vine-ripened tomatoes. Even more, I love how this vegetable (yes, botantists call it a fruit) can transform a simple recipe into a savory, mouth-watering dish. Francesca’s homemade marinara sauce is one of them, and when its aroma fills the air, you know you’re in for a treat. What’s more, how she prepares her culinary masterpiece actually boosts its nutritional value, according to new research.
