Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Plum Custard Tartlets
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Sieve the greengage plums into a bowl.
Whisk together the sieved plums, sugar, and egg yolks until light and foamy.
Assemble and bake
Fill small puff pastry shells with the plum mixture.
Beat the egg whites until stiff.
Fold the powdered sugar into the beaten egg whites.
Spread the meringue over the plum filling.
Bake in a preheated oven at 350°F (175°C) until lightly browned.
Serve
Allow the tartlets to cool for easy handling.
Serve the tartlets warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Greengage plums
- Provide the main fruit flavour and a juicy, tart base for the custard filling.
- Sugar
- Sweetens the plum filling and helps it set smoothly when cooked.
- Egg yolks
- Thicken the plum mixture and give the filling a rich, creamy structure.
- Egg whites
- Whip into a stiff foam that forms the meringue topping.
- Powdered sugar
- Dissolves into the whites to stabilise the meringue and add sweetness.
The step that matters
Beating the egg whites until stiff. Egg whites need to form a firm foam without being overbeaten, since under-whipped whites will weep or sink and overbeaten whites turn grainy and dry. Grease or yolk residue in the bowl prevents whites from reaching full volume.
Swap the plum
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Plumthe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
