Why it works: Lemon and chestnut match in chemistry and in kitchens. They rank in the top 11% of all ingredient pairs, and cooks put them together in 381 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Chestnut Amber
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the base
Preheat the oven to 350°F (175°C).
Combine milk, eggs, lemon juice, chestnut puree, breadcrumbs, and caster sugar in a bowl.
Pour the mixture into a baking dish and bake until set.
Make and add the meringue
Whisk the egg whites until stiff peaks form, then gradually add sugar to make meringue.
Spread the meringue over the baked mixture and sprinkle with icing sugar.
Return to the oven until the meringue is nicely browned.
Serve
Serve hot or cold.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard and help bind the base together.
- Milk
- Provides the liquid that gives the base a soft, custard-like texture.
- Breadcrumbs
- Absorb liquid and give the base body so it holds together.
- Chestnut puree
- Adds the main chestnut flavour and thickness to the base.
- Caster sugar
- Sweetens the base and helps stabilise the whisked meringue.
- Lemon
- Adds acidity and fresh citrus aroma to balance the sweetness.
The step that matters
Whisking the meringue. Adding sugar gradually to the egg whites lets it dissolve and stabilise the foam. Adding it too quickly, or letting any fat into the whites, can stop them reaching stiff peaks, so the meringue may weep or collapse in the oven.
