Why it works: Bread and butter match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,145 recipes mention both. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the base
Rub the bread crumbs through a fine sieve.
Add the wine and water mixture, grated lemon rind, sugar, and butter. Mix well.
Pour the mixture into a buttered soufflé dish.
Add the beaten egg yolks and strained lemon juice. Mix to combine.
Make the meringue
Beat the egg whites with a pinch of salt until stiff. Add sugar to taste.
Color the egg whites with spinach greening or carmine if desired.
Pile the egg whites on top of the mixture in the dish.
Bake
Bake in a moderate oven at 350°F (175°C) until the meringue is set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread crumbs
- Form the body of the pudding and soak up the liquid to give it a soft, tender base.
- Egg yolks
- Enrich the base and help it set into a custard-like texture when baked.
- Egg whites
- Whip into a foam that bakes into a light, set meringue topping.
- Butter
- Adds richness and a tender texture to the base.
- Sugar
- Sweetens the base and helps stabilize the beaten egg whites.
The step that matters
Beating the egg whites until stiff. Egg whites must be whipped until they hold firm peaks; under-beaten whites collapse and weep, while over-beaten whites turn dry and grainy. Stiff, glossy foam gives the meringue its lift and light texture in the oven.
Flavor stand-ins for the spinach
The recipe marks spinach as optional. How well each one fits the dish's main ingredients (bread, wine, lemon, sugar, butter, egg):
- Asparagusbetter flavor fit
- Tomatobetter flavor fit
- Capsicumbetter flavor fit
- Spinachthe original
Fit is the average pairing score against bread, wine, lemon, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
