Creamy Tomato Sauce
I found this on FoodNetwork as well. Its a Giada recipe. I already have a few containers of homemade marinara so I used that in place of store bought marinara.
1 cup purchased marinara sauce
1/2 cup whole-milk ricotta cheese
Salt and freshly ground black pepper
Bring the marinara sauce to a simmer in a medium saucepan over medium heat, whisking often. Whisk in the ricotta and enough reserved cooking water to thin the sauce to desired consistency. For a thicker sauce, use less pasta water; for a thinner sauce, add more water. Return the sauce to a simmer. Season the sauce to taste with salt and pepper.
I can't entirely place what was "wrong" with this dish. I was expecting more flavor from the ravioli, so I don't know if my sauce overpowered it or what. I do think I can build on this recipe though, use the same filling, more spices, homemade ravioli & probably use a Vodka Sauce as opposed to a creamy tomato sauce.
