The flavor team

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 base and, whipped, the light frothy topping.
French rolls
Soak up the cream and wine, giving the dish a soft, layered body.
Currant jelly
Adds fruity sweetness and tartness between the layers.
Hartshorn jelly
Sets into a firm layer that gives structure between the rolls.

The step that matters

Whipping the cream with sack and lemon zest. Cream must be whipped to the right thickness: under-whipped it stays runny and won't hold its froth, while over-whipped it turns grainy and can separate. The froth must be thick enough to heap 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.
