Tomato Souffle

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the base

  1. Melt the butter in a saucepan.

  2. Stir in the flour, then gradually add the milk.

  3. Add the seasonings, grated cheese, and tomato pulp.

  4. Mix in the egg yolks.

Fold and bake

  1. Fold in the stiffly beaten egg whites.

  2. Pour into a buttered baking dish and place it in a larger dish filled with hot water.

  3. Bake at 400°F (200°C) for about 30 minutes.

  4. Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Whites trapped by folding give the soufflé its light, risen structure; yolks enrich the base.
Flour
Thickens the melted butter and milk into a sauce that holds the soufflé together.
Butter
Fat that forms the roux with the flour and adds richness to the base.
Milk
Liquid that, with the flour and butter, forms the thick base for the soufflé.
Tomato pulp
Adds moisture and tomato flavour to the base.

The step that matters

Fold in the stiffly beaten egg whites. Folding gently keeps the air in the whites. Stirring or overmixing deflates the foam, so the soufflé rises less and turns dense.

Swap the tomato

Fit is the average pairing score against butter, flour, cheese, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
