Christopher Kimball heads to Calabria in search of pasta recipes based on the simplest of ingredients. First up, it's Spaghetti with Garlic and Walnut Breadcrumbs. Then, we learn about Calabrian chilis while making Pasta with Sun-Dried Tomato and Red Pepper Pesto. Finally, we make Pasta with "Fake" Sauce, so-named because it mimics a deeply-flavored ragu without any meat.
