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 ↓
Greengage 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
Preheat the oven to 350°F (175°C).
Assemble the tart
Select sound greengage fruit and fill a pie dish with them.
Dissolve powdered sugar in enough spring water to make a syrup, then pour it over the fruit.
Cover the fruit with puff pastry.
Brush the crust with the egg yolk.
Bake and serve
Bake in the oven for a few minutes until golden.
Sprinkle powdered sugar over the top before serving.

What each ingredient does
- Greengage fruit
- Provides the main flavour and juicy filling, with tartness from the not-quite-ripe fruit.
- Powdered sugar
- Dissolves into the spring water to form a syrup that sweetens the fruit and moistens the filling.
- Puff pastry
- Forms a flaky, layered crust that rises and crisps in the oven.
- Egg yolk
- Brushed on the crust to promote browning and a glossy golden finish.
The step that matters
Brushing the crust with egg yolk. Egg yolk contains proteins and fats that brown and shine in the oven. Applying it evenly gives a uniform golden colour, while pooling or missing patches can leave the crust pale or unevenly coloured.
