Make this when it’s Sunday and you’re not leaving the house. One spoonful of this smoky-spicy guajillo braising liquid and you’ll understand how complex dried chiles can be. When soaked in hot water and blended with aromatics, they create a base so flavorful you don’t even need stock. The chile purée may seem like a lot of liquid at first, but don't worry: Keeping the pot slightly uncovered as the ribs cook will allow the sauce to reduce and concentrate.
