Fish Dinner

I wanted a fast and easy dinner last night. Nothing is quite as fast as fish, and this was very easy. I think the idea came from one of Pierre Franey's cookbooks, but don't quote me on that.

FISH IN MUSTARD SAUCE

1 pound white fish fillets
salt & pepper to taste
2 tbsp butter
2 scallions, chopped
1 tbsp cornstarch
1 tbsp dijon mustard
1/2 cup heavy cream
1/2 cup milk

Melt the butter in a skillet. Season with salt and pepper and cook the fish until done, then remove it to a plate and put a pan lid over it to keep it hot. Saute the scallions in the butter in which the fish was cooked for a minute, then whisk in the cornstarch and mustard. Whisk in the milk and cream, and cook until thickened. Put the fish back in the skillet for a minute to reheat, and serve over a bed of rice.
When my husband asked what made this fish sauce taste so good, my little guy piped up that Mommy had put "grey pop-on" in it. I didn't correct his mispronunciation, thinking that telling him it's actually "grey poop-on" would cause gales of laughter among the 9 to 12 year old set.
