Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the custard

  1. Beat the butter and sugar until light and fluffy.

  2. Gradually add the crumbled sponge cake.

  3. Whisk the eggs until thick, then stir them in gradually.

  4. Add the lemon juice, grated rind, brandy, and rose-water in two parts, mixing thoroughly without over-beating.

Bake

  1. Line pie plates with puff pastry or pie crust.

  2. Fill the crusts with the custard mixture and bake until set.

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

What each ingredient does

Eggs
Whisked eggs thicken and set the custard as it bakes, giving it structure.
Butter
Beaten with sugar, it traps air and adds richness and a tender texture.
Sugar
Creamed with butter for a light base and adds sweetness to the filling.
Stale sponge cake
Crumbled into the batter, it soaks up liquid and adds body to the filling.
Lemon juice and rind
Provide acidity and bright aroma that cut the richness of the butter and eggs.

The step that matters

Mixing the liquids in two parts without over-beating. Adding the lemon juice and liquors gradually keeps the mixture emulsified. Over-beating incorporates too much air, which can make the custard rise, crack, or turn uneven as it sets.

Swap the lemon

How well each one fits the dish's main ingredients (butter, sugar, egg, brandy, rose):

  1. Vanillafits better
  2. Currantfits better
  3. Raspberryfits about as well
  4. Lemonthe original

Fit is the average pairing score against butter, sugar, egg, brandy, rose. Candidates are from the same food group and used in at least 100 recipes.
