Floating Island

Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Floating Island

Ingredients

Directions

Prepare the cream

  1. In a large bowl, sweeten the cream with fine sugar.

  2. Add the sake and grated lemon rind, then whip the cream until thick and frothy.

Layer the dish

  1. Carefully pour the thin liquid from the froth into a dish.

  2. Slice the French rolls as thinly as possible and layer them on the cream.

  3. Add a layer of currant jelly, followed by another thin layer of roll, then hartshorn jelly, and repeat the layering.

  4. Top with the saved froth, heaping it as high as possible.

Decorate

  1. Decorate the rim of the dish with figures, fruits, or sweetmeats.

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
Whipping traps air, giving the light, frothy structure that forms the topping.
French rolls
Thin slices soak up the liquid and build soft, tender layers between the cream.
Currant jelly
Adds sweetness and tart fruit flavour to each layer.
Yellow rind of 1 lemon
Contributes bright citrus aroma to the cream.
Sack (or sweet wine)
Adds sweetness and wine flavour to the cream base.

The step that matters

Draining the thin liquid and saving the froth. Pouring off the thin liquid carefully keeps the whipped froth intact. Froth holds its shape only when undisturbed, so a collapsed topping will not heap high over the layers.

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.
