This video shows you the procedure for making a basic red sauce for pasta. Chef John calls this a “procedure” rather than a recipe video because it’s never the same twice. It usually involves a combination of meats, thoroughly browned in the oven. Basically, any combination of meats will work. Here, it includes beef shank, pork ribs, and chicken thighs. The browned meats will simmer in the tomato sauce until they're so tender the meat falls right off the bones. Watch the video, then get the recipe for Chef John's Sunday Pasta Sauce. Serve it over pasta topped with freshly grated Parmesan.
