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
Whips into the airy froth that forms the floating top layer.
Sugar
Sweetens the cream and helps stabilise the whipped froth.
French rolls
Soak up the cream and wine, giving the dish a soft, spongy body.
Currant jelly
Adds fruity sweetness and tartness between the bread layers.
Hartshorn jelly
Sets into a firm layer that adds body between the rolls.

The step that matters

Pour off the liquid from the froth. Carefully separating the thin liquid from the whipped froth keeps the base from becoming watery, so the froth stays light and can be heaped high on top.

Swap the currant

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

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

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