Ina's Mustard Roasted Fish

Made this tonight for dinner and I'm really happy to have another way to prepare fish! Ina's recipe called for red snapper, however, I used tilapia. I also served it on top of rice with a baked potato and salad.
In a small bowl mix together: 8oz creme fraiche (or sour cream, not low fat), 3 tbsp dijon mustard, 1 tbsp whole grain mustard, 2 tbsp minced shallots, 1 tsp drained capers. Salt and pepper both sides of the fish fillets. Put in baking dish and cover each fillet with mustard mixture. Bake 13 minutes at 425 degrees. Enjoy!
