1 tsp dried thyme, or 2 tsp fresh thyme or rosemary (or combo)
1 28oz can of Italian plum tomatoes
1 cup stock or water
1 cup heavy cream
salt and pepper, to taste
Preparation
Slowly heat butter in the bottom of a heavy pot. Add onions and let cook on low until extremely soft and sweet, 10-15 minutes. Really try not to let these brown.
When onions are really nice and soft, add the boat sauce. You may want to turn up the heat a little to really seal in the flavor here, but keep your eye on it and don't let it burn. Stir consistently.
Add herbs and a pinch of salt, then the tomatoes, stock and cream. Turn the heat up until it's at a low boil or high simmer, and cook for about 10 min.
Process in a blender or with a hand mixer, then return to the pot and add salt and pepper to taste.
It would just be silly to not serve this with some kind of grilled cheese sandwich. I also recommend a garnish of purple kale chips, if you happen to have some lying around.
