A good way to add big flavor to sauces is to roast a whole bulb of garlic and add the mashed cloves to your sauce.
Mash Garlic with salt, ricotta, lemon, red pepper flakes, and black pepper for your sauce base!
The key ingredient to making this sauce work is very hot pasta water. Cook your pasta (I like fusilli) and then reserve about two cups of HOT pasta water.
Stir the hot water into the sauce base to form a rich and creamy pasta sauce. Use it immediately on your pasta!
