Onion Souffle

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

  1. Soak the bread crumbs in the milk.

  2. Add the white sauce, onions, pepper, and salt.

  3. Mix in the beaten egg yolks.

  4. Fold in the beaten egg whites last.

  5. Pour the mixture into a buttered pudding dish.

  6. Bake at 300°F (150°C) for 45 minutes.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
