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
Preheat the oven to 350°F (175°C).
Make the filling
Whisk together the sieved plums, sugar, and beaten egg yolks until light and foamy.
Fill small puff pastry shells with the plum mixture.
Top and bake
Beat the egg whites until stiff, then add powdered sugar and spread over the plum filling.
Bake the tartlets in the oven for a few moments until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the plum mixture into a custard as they set with heat.
- Egg whites
- Whipped into a stiff meringue topping that browns during baking.
- Sugar
- Sweetens the plum custard and balances the tartness of the fruit.
- Green gage plums
- Provide the fruit flavour and tartness for the custard filling.
- Puff pastry
- Forms the crisp shell that holds the custard filling.
The step that matters
Beat the egg whites until stiff. Egg whites must be whipped to stiff peaks to hold their volume and form a light topping; under-whipped whites spread flat and weep, while the sugar added afterward helps stabilise the foam.
