Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Prune Souffle
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the prune pulp
Prepare prunes by stewing them in a double boiler with cold water until tender.
Press the pulp through a sieve.
Add sugar to the pulp, cook for 5 minutes, then cool and add lemon juice.
Make the soufflé
Beat the egg whites until stiff, then gradually fold in the prune mixture.
Transfer to a buttered baking dish and bake in a 300°F (150°C) oven for 30 to 40 minutes; test with a knitting needle.
Serve
Serve hot or cold with cream or custard sauce.
The mixture can also be served without cooking.
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.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Prunes
- Provide the main body, sweetness and flavour of the soufflé.
- Egg whites
- Whipped to stiff foam, they give the soufflé its light, risen structure.
- Lemon juice
- Adds acidity that brightens the sweet prune flavour.
- Sugar
- Sweetens the prune pulp and balances its tartness.
The step that matters
Folding the prune mixture into the egg whites. Stiff whites hold the soufflé's air; folding gently keeps that air in, while overmixing deflates the foam and leaves a dense result.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
