In sauce pan, heat the olive oil over medium heat. Add the onions, parsley, and red pepper flakes, and saute until the onion is tender, 6 to 8 minutes. Add the garlic pulp and mix well. Stir in the tomato sauce, stock, cream, salt, and pepper. Bring to a boil, then simmer until the mixture reaches a saucelike consistency, about 10 to 12 minutes. This sauce is a good condiment for pasta but is even better as a dipping sauce. Try it chilled with your favorite fried finger foods, or as a twist on the traditional shrimp cocktail sauce.
