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.

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

What each ingredient does

Thick cream
Forms the rich, creamy base and the whipped top layer that gives the dish its height.
French roll
Soaks up the sweet cream and gives the layers body and structure.
Calves-feet jelly or currant jelly
Sets into a firm layer and adds fruity sweetness.
Sweet white wine
Adds sweetness and a light, fragrant acidity to the cream.
Lemon peel
Adds aromatic citrus oils that scent the cream.

The step that matters

Whipping the remaining cream to hold its height. Cream traps air only up to a point. Under-whipped cream slumps under its own weight, while over-whipping makes it grainy and begin to separate, so it needs to be stopped at stiff peaks.

Swap the currant

How well each one fits the dish's main ingredients (cream, sugar, lemon, white wine):

  1. Orangefits better
  2. Vanillafits better
  3. Raspberryfits better
  4. Currantthe original

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