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

What each ingredient does

Thick cream
Provides the rich body and fat that the whisked froth is built on.
Egg whites
Whisked into foam, they trap air and give the syllabub its light, airy texture.
Brandy
Adds alcoholic aroma and flavour that balances the sweetness of the dish.
Lemon juice
Adds acidity that brightens the rich cream and cuts its sweetness.

The step that matters

Whisking the egg whites for an hour. Egg white foam must be whisked enough to hold air, but over-whisking can break it down and make it grainy. Watching the froth as it rises helps the cook judge when it is ready to drain.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits better
  3. Raspberryfits better
  4. Lemonthe original

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