Soupe A L'Oignon(French Onion Soup; France.) - cooking recipe

Ingredients

4 Tbsp. butter
2 Tbsp. vegetable oil
2 lb. onions, thinly sliced (about 7 c.)
1 tsp. salt
3 Tbsp. flour
2 qt. beef stock (fresh or canned) or beef and chicken stock, combined

Preparation

In a heavy 4 to 5-quart saucepan or soup kettle, melt the butter with the oil over moderate heat. Stir in the onions and teaspoon salt and cook, uncovered, over low heat, stirring occasionally for 20 to 30 minutes or until the onions are a rich golden brown. Sprinkle flour over the onions and cook, stirring, for 2 or 3 minutes. Remove the pan from the heat. In a separate saucepan, bring the stock to a simmer, then stir the hot stock into the onions. Return the soup to low heat and simmer, partially covered, for another 30 to 40 minutes, occasionally skimming off the fat. Taste for seasoning and add salt and pepper if needed.
