I hate to disappoint the French but they cannot cook mussels. This recipe is the best ever for mussels not only are they tasty but the "soup" at the end is delicious.
Chopped, 2 onions, 4 cloves garlic, 1 inch of ginger, 1 hot pepper
saute chopped ingredients in a little oil until softened add
1 tomato chopped, 1 tsp each of cumin, coriander, chilli let cook for 3 minutes
add cup of water and tsp salt let cook for 5 minutes
add cleaned mussels cook for 10 minutes
sprinkle with 1/2 cup chopped fresh coriander and half a lemon squeezed
stir and serve with crusty bread and butter or white jasmine rice
