Why it works: Milk and lemon are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Baked Custard
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 the custard
Warm the milk and sugar in a saucepan until the sugar is dissolved.
Pour the warm mixture onto the beaten eggs and add the grated lemon rind or nutmeg for flavor.
Assemble and bake
Line a pie dish with the short pastry.
Pour the custard mixture into the pastry-lined dish.
Bake in a moderate oven at 350°F (175°C) until set.
Serve
Serve hot or cold.

Sugar and lemon 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
- Milk
- Forms the liquid base of the custard, giving it body and a soft, creamy texture.
- Eggs
- Set during baking to give the custard its structure and firm, sliceable texture.
- Sugar
- Sweetens the custard and helps it stay tender and smooth as it sets.
- Short pastry
- Forms the crisp shell that holds the liquid custard as it bakes.
The step that matters
Bake until just set. Eggs thicken as their proteins coagulate with heat. Overbaking squeezes out liquid and makes the custard grainy and watery, so it should be removed once the centre barely wobbles.
Swap the lemon

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