Tomato sauce could be called boring.
Or it could be called simple.
2 sm or 1 lg onion, chopped
2 shallots, chopped
5 + cloves garlic, chopped
3 dried chilies, crumbled
1 tsp fennel seed
1/2 oz.can tomatoes, chopped with juice
Saute onions, shallot and garlic in olive oil over medium heat until translucent. Add balsamic, stir for a few seconds and add chiles and fennel seed. Saute until chili skins darken.
Add tomatoes. Bring to a nice simmer and turn the heat down to low. Add Bragg's to taste (maybe about a tsp, but start less and work up). Cook, partially covered, until sauce thickens. Perhaps 20 min.
Done and done.
One thing about tomato sauce is that you really need to add a little sugar to it to cut the acid in the tomatoes, but I don't like sweet tomato sauces and it can be hard to hit the right balance. In this case, the balsamic adds a little sweetness and a nice round flavor. Sugar tastes just sweet. Flat sweet. This is a nice interesting sweet. I like the added flavor of the shallots as well. It complicates the onions. Onions should be complicated to compensate for the simplicity of the sauce overall.
