Mustard seed, when popped in hot oil, release a sweet and nutty flavor akin to popcorn. But when ground and turned into a paste with hot water, the same seeds breathe pungent fire. Include the two techniques in the same recipe, and watch a brilliant balance of tastes, textures and colors come alive in every mouthful. Serve a bowl of this stew with crusty-warm slices of baguette or even steamed basmati rice for a quick weekday fare.
This versatile recipe can be made into smaller patties as an appetizer, using the mustard-yogurt sauce on the side as a dip. It can also be served on a plate with a green salad, or in a whole-wheat pita. Do not boil sweet potato as that will add excess moisture to patties.
