Not sure what the source is but V and I make this sauce usually on week nights. It's the most bang for the buck kind of a dish. And no picture because it looks like tomatoey pasta sauce :)
1 large onion chopped
4 cloves of garlic, chopped
crushed red pepper
2 1/2 cups of diced tomatoes
1 small can of tomato paste
1 cup vodka - get a good brand of vodka because the flavor really pulls through into the sauce even though most of the alcohol is cooked off.
1/2 cup cream
salt and pepper to taste
Heat oil and add garlic, crushed red pepper and onions. Cook until onions are translucent. Now add the tomato paste and cook for a minute. Now add diced tomatoes and cook until tomatoes are cooked, about 10 mins. Now vodka, cover and cook for another 15 mins. Lastly stir in cream, salt and pepper. Cook for another 3-5 mins. This is a good time to add pasta that is cooked shy of al dente to the sauce so that it finishes cooking in the sauce itself.
Garnish with grated parmesan cheese.
