Add the tomato paste and stir for 1-2 minutes with a wooden spoon. Then, whisk in the heavy cream until well combined and bring the mixture to a boil.

Reduce the heat to low and let the sauce simmer for 30-60 seconds. Next, mix in the butter, salt, pepper, and pepper flakes (if using). Stir in the vodka.
