spaghetti alla vodka

1 lb spaghetti or pasta of choice
olive oil
1/2 of small onion--finely diced
2 garlic cloves--finely diced
6-8 basil leaves--chiffonade
1 large tin peeled whole tomatoes or combination of vodka soaked tomatoes and tinned tomatoes to equal about 4 cups whole
1/2-1 tsp crushed red pepper flakes
1/2 cup tomato soaked vodka (or other vodka you have on hand)
1/2 cup heavy cream
1/4 cup grated parmesan plus more for serving

cook pasta in salted water,  according to package instructions.  cook onions and garlic in olive oil over low heat.  meanwhile, place the tomatoes in a food processor or blender and pulse until it is smooth.  do not allow the onions and garlic to brown, but let them begin to soften and become translucent. at this point, add the tomatoes and vodka and let simmer for about  10-15 minutes.  add the basil, red pepper flakes and heavy cream and allow to heat through.  stir in parmesan, then toss drained pasta in.  if the sauce seems too thick,  use a bit of the pasta water.  shave a bit of parmesan on top of each individual serving, along with additional crushed red pepper, if you like spicy.
