Why it works: Orange and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 4,696 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Orange Tart
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.
Make the filling
Beat the yolks of 4 eggs with 8 tablespoons of sugar.
Add the juice and grated rind of 2 oranges and ⅔ cup of milk.
Pour the mixture into a prepared pie crust and bake at 350°F (175°C) for 30 minutes.
Make the meringue and finish
For the meringue, beat the whites of 4 eggs with 4 tablespoons of icing sugar until firm.
Spread the meringue over the baked tart.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the orange filling as they set, giving it a rich, custard-like body.
- Sugar
- Sweetens the filling and helps balance the sharpness of the orange juice.
- Orange juice and rind
- Provide acidity and bright citrus aroma to the filling.
- Milk
- Adds moisture and softness to the filling.
- Egg whites
- Whip into a stable, airy meringue topping.
- Icing sugar
- Sweetens the meringue and helps it whip into a firm, glossy structure.
The step that matters
Beat the egg whites until firm. Whites must be whipped until they hold stiff peaks; under-whipped whites will weep or slump on the tart, while any trace of yolk or fat in the bowl will stop them foaming properly.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, milk):
- Vanillafits better

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