Don't let the recipe title fool you..... this is a creamy, elegant way to serve mussels. The flavor combination of cream, mustard and saffon is great. This recipe will easily double, triple, and quadruple. Mussels make a perfect appetizer served with crusty bread for sopping up the sauce or as a light meal by themsleves with a small salad, crusty bread and some wine. A good rule of thumb for mussels is 1/2 lb per person as an appetizer, 1 to 1 1/2 lbs per person as an entree'. Preparation time includes cleaning the mussels.
