Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the pulp

  1. Stew the tomatoes well and drain off the juice.

  2. Rub the pulp through a sieve.

Make the batter

  1. Beat the egg whites and yolks separately.

  2. Mix the yolks with the pulp and season with salt and pepper.

  3. Gently fold in the beaten egg whites.

Bake and serve

  1. Pour the mixture into a buttered baking dish.

  2. Bake at 400°F (200°C) for 10 to 15 minutes.

  3. Serve immediately.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Pepper and egg barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Whipped whites trap air for lift, while yolks add richness and help set the custard.
Tomato pulp
Provides the main flavour and moisture, forming the base the eggs are folded into.

The step that matters

Gently fold in the beaten egg whites. Folding rather than stirring keeps the air bubbles in the whipped whites intact. Those bubbles are what make the soufflé rise, so overmixing causes it to fall and turn dense.

Swap the tomato

How well each one fits the dish's main ingredients (pepper, egg):

  1. Capsicumfits better
  2. Spinachfits better
  3. Asparagusfits better
  4. Tomatothe original

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