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 Tart
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
Line the edge of a tart dish with puff pastry or short crust pastry.
Fill the dish with plums and sprinkle a little moist sugar over them, adjusting the amount based on the plums' quality.
Bake and glaze
Cover the dish with pastry and bake in a moderate oven at 350°F (175°C).
For a glazed finish, remove the tart from the oven before it is fully done.
Brush the tart with whisked egg white and sprinkle with finely sifted sugar.
Add a few drops of water and return the tart to the oven to set the glaze.
Alternatively, brush the tart with cold water and sprinkle with white sugar before baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plums
- Provide the fruit filling and its juices, which soften and sweeten during baking.
- Moist sugar
- Sweetens the plums and draws out some of their juice.
- Egg white
- Brushed on top, it forms a glossy, lightly set glaze.
- Puff pastry or short crust pastry
- Forms the tart case and top crust, providing structure and flaky or crisp texture.
The step that matters
Removing the tart before it is fully done. For a glazed finish, the tart leaves the oven early so the egg white glaze can be applied and set without over-browning or drying the fruit. Pulling it too late can leave the glaze dull and the pastry overcooked.

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