SOUPE À L’OIGNON [Onion Soup]
The onions for an onion soup need a long, slow cooking in butter and oil, then a long, slow simmering in stock for them to develop the deep, rich flavor which characterizes a perfect brew. You should therefore count on 2½ hours at least from start to finish. Though the preliminary cooking in butter requires some watching, the actual simmering can proceed almost unattended.

Instructions
  1. Cook the onions slowly with the butter and oil in the covered saucepan for 15 minutes.
  2. Uncover, raise heat to moderate, and stir in the salt and sugar. Cook for 30 to 40 minutes stirring frequently, until the onions have turned an even, deep, golden brown.
  3. Sprinkle in the flour and stir for 3 minutes.
  4. Off heat, blend in the boiling liquid. Add the wine, and season to taste. Simmer partially covered for 30 to 40 minutes or more, skimming occasionally. Correct seasoning.
  5. (*) Set aside uncovered until ready to serve. Then reheat to the simmer.
  6. Just before serving, stir in the cognac. Pour into a soup tureen or soup cups over the rounds of bread, and pass the cheese separately.
