In a saucepan over medium heat, sauté the minced garlic and chopped onion in 2 tablespoons of butter and 2 tablespoons of olive oil until the mixture is soft.
Pour in the vodka, being careful if your stove has an open flame. Remove the pan from the heat before adding the vodka if necessary. Cook and reduce the mixture for 2 to 3 minutes.
Pour in the tomato puree or tomato sauce, and stir the mixture until it's thoroughly combined. Reduce the heat to low.
Pour in the heavy cream, and stir to combine. Turn the heat to the lowest simmer possible.
Sprinkle in the red pepper flakes, and add salt and pepper to taste.
Finally, stir in the remaining 1 tablespoon of butter. Pour the drained pasta into the sauce and toss to combine.
Sprinkle grated Parmesan over the top of the pasta and sauce, and add more red pepper flakes if desired.
