Why it works: Raspberry and lemon are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,109 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Sponge Cake in Custard
Ingredients
Directions
The book says “a cool oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the base
Preheat the oven to 350°F (175°C).
Layer stale sponge cake or lady fingers in a small, shallow dish.
Spread jam over the cake.
Make the custard
Scald the milk.
In a bowl, beat the egg yolks, then add granulated sugar and lemon rind.
Pour the scalded milk over the egg mixture and stir well.
Pour the custard over the cake.
Bake for about 20 minutes, until the custard is set.
Make the meringue and finish
Remove from the oven and beat the egg whites until stiff.
Add powdered sugar to the egg whites and beat well.
Heap the meringue on top of the custard and bake for an additional 15 minutes in a cool oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set during baking.
- Egg whites
- Whipped into a stiff foam that forms the meringue topping and sets light and airy.
- Milk
- Provides the liquid base that the eggs set into a smooth custard.
- Sponge cake or lady fingers
- Forms the absorbent base that soaks up the custard as it bakes.
- Granulated sugar
- Sweetens the custard and helps stabilize the egg yolks.
- Powdered sugar
- Dissolves easily into the whipped whites to sweeten and stabilize the meringue.
The step that matters
Beating the egg whites until stiff. Egg whites must be whipped to stiff peaks with no trace of yolk or grease, or the foam will not hold. Folding in the sugar gradually keeps the meringue glossy and stable during baking.
Swap the raspberry
How well each one fits the dish's main ingredients (milk, egg, sugar, lemon):
- Vanillafits better
- Orangefits about as well
- Figfits about as well
- Raspberrythe original
Fit is the average pairing score against milk, egg, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
