Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Orange Tart
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Line a buttered dish with puff pastry.
Make the filling
Beat the butter and ¼ cup sugar until creamy.
Add cake crumbs, egg yolks, milk, grated orange rind, and orange juice; mix well.
Pour the mixture into the prepared pastry and bake for about 30 minutes.
Top and serve
Beat the egg whites until stiff, then gently fold in ¼ cup sugar.
Spread the egg white mixture on top of the tart and sprinkle with chopped nuts.
Return to the oven until the top is golden brown.
Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the filling and help it set into a custard-like texture.
- Egg whites
- Whipped into a meringue topping that gives a light, golden crust.
- Butter
- Adds richness and tenderness to the filling mixture.
- Cake crumbs
- Soak up liquid and give the filling body and a soft, tender texture.
- Orange juice
- Provides acidity and bright citrus flavour to the filling.
- Sugar
- Sweetens the filling and helps stabilise the whipped egg white topping.
The step that matters
Beating the egg whites until stiff. Under-whipped whites will not hold a peak and the topping will deflate or spread. Over-whipped whites turn dry and grainy and crack in the oven. Folding gently keeps the air in the foam.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, nuts):
- Vanillafits better
- Coconutfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, egg, milk, nuts. Candidates are from the same food group and used in at least 100 recipes.
