Why it works: Peach and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,308 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Peach Custard
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Place the halved peaches in a baking dish and sprinkle with powdered sugar.
Bake and finish
Pour the custard over the peaches and bake for 20 minutes.
Spread the beaten egg whites over the top, sweetening to taste.
Return to the oven until the top is light brown.
Serve warm with a rich sauce or cold with sweetened cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Provide the fruit base and fresh, sweet flavour that the custard covers.
- Egg whites
- Beaten whites set and brown on top, giving a light, airy topping.
- Custard
- Forms the creamy, set layer that bakes around the peaches.
- Powdered sugar
- Dissolves quickly into the fruit, adding sweetness and helping it caramelise lightly.
The step that matters
Spreading the egg whites and returning to the oven. Beaten egg whites must be spread over the top so they seal the surface and then brown evenly. Watch them closely: egg white proteins set and colour quickly, so over-baking can make the topping dry, tough, or overly dark.
Swap the peach

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