Ingredients

Directions

Prepare the cream

  1. Sweeten the cream with fine sugar and pour in the sake.

  2. Grate the lemon rind into the cream and whip it to a thick froth.

  3. Carefully pour the thin part from the froth into a dish.

Layer the dish

  1. Layer thin slices of French bread on the cream, followed by currant jelly.

  2. Add another layer of French roll, then hartshorn jelly, and more French roll.

Finish and decorate

  1. Top with the whipped froth, heaping it as high as possible.

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

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

What each ingredient does

Thick cream
Whipped into a stable foam that forms the light, airy topping.
Sack
Adds a fragrant, lightly sweet wine flavour to the cream.
Lemon rind
Adds bright aroma that cuts through the richness of the cream.
French bread
Soaks up moisture from the cream and jelly, giving the layers body.
Currant jelly
Adds sweetness and tart fruit flavour between the layers.
Hartshorn jelly
Sets as a gelling agent, giving the middle layer a firm, sliceable texture.

The step that matters

Pouring off the thin part of the froth. Only the stiff foam should top the dish. Thin liquid left in the whipped cream would seep down through the bread and jelly layers, making them soggy and loosening the heaped topping.

Swap the currant

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

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

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