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
Preheat the oven to 350°F (175°C).
Sieve the greengage plums into a bowl.
Whisk together the sieved plums, sugar, and egg yolks until light and foamy.
Bake and top the tartlets
Fill small patty pans with puff pastry and bake until light brown.
Fill the baked pastry shells with the plum mixture.
Beat the egg whites until stiff, then add powdered sugar and spread over the plum filling.
Return the filled shells to the oven for a few moments until the meringue is set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Greengage plums
- Provide the fruit flavour and tart acidity that balance the sweet custard.
- Sugar
- Sweetens the plum mixture and helps give it a smooth, set texture.
- Egg yolks
- Thicken the plum mixture into a creamy custard as they cook.
- Egg whites
- Whip into a stiff foam that forms the meringue topping and sets in the oven.
- Powdered sugar
- Dissolves easily into the whipped whites to sweeten and stabilise the meringue.
The step that matters
Returning the filled shells to the oven. Meringue sets and browns quickly in the heat, so it can scorch or weep if left too long. Watch it closely and remove it once it is just set.
Swap the plum

- Vanillafits better

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