This recipe is mine, based on my first lessons on making a good sauce. It's the traditional style of marinara sauce. I almost always use this method except in winter when I can't get good basil and the veggies aren't as fresh.
2 sweet onions finely diced
2 carrots finely diced
2 stalks of celery from the heart, finely diced
4 cloves of garlic minced
1/2 c extra virgin olive oil
2 (28oz) cans crushed tomato's
1 c water
2 good handfuls of basil and chopped roughlySalt and Pepper to taste
Heat olive oil in a heavy bottomed pan on medium-high heat. Add onions and garlic and saute about 7 minutes until translucent. Add celery, carrots and season with salt and pepper liberally. Stir occasionally, and cook for about another 7 minutes. When vegetables are tender, add tomatoes and water. Allow to cook on medium low heat for about 1 1/2 hours.
Add basil to sauce and serve.
