Poached Fish Fillets With Rich Wine Sauce - cooking recipe

Ingredients

4 large or 8 small fish fillets
1 part dry white wine and 1 part water (enough to cover fillets)
1 onion, sliced
tarragon to taste
grated Parmesan cheese
4 Tbsp. margarine or butter
4 Tbsp. flour
1 c. milk (for richer sauce, use evaporated skim milk)
salt and pepper to taste

Preparation

In a shallow pan or skillet, bring to a boil enough wine and water to cover the fish, adding a pinch of salt, tarragon and the sliced onion.
Add the fillets and simmer gently (do not boil) until fish flakes easily.
This will take about 5 minutes.
Test for doneness with a fork or toothpick.
