I needed an alfredo sauce the other night and found this one (I think it was at cooks.com). It is fabulous!! Very fattening but so good!!
1/4 cup butter
1 cup cream
1 clove garlic, minced finely
1 1/2 cups parmesan cheese
1/4 cup fresh parsley, chopped
Melt butter over medium low heat. Add the cream. Simmer 5 minutes. Add garlic and parmesan. Whisk quickly. Stir in parsley and serve.
Now parmesan does not tend to melt very well. So I used a 5 cheese Italian blend which worked perfectly.
