Why it works: Lemon and almond match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 5,655 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Very Good Old-fashioned Boiled Custard
Ingredients
Directions
Prepare the milk
Infuse the lemon rind in 1½ pints of new milk for 30 minutes.
Simmer the milk for a few minutes, then add 4½ ounces of sugar.
Make the custard
Beat the yolks of 14 eggs and mix with ½ pint of new milk.
Stir the boiling milk quickly into the egg mixture and remove the lemon peel.
Pour the custard into a deep jug and place it over boiling water.
Stir gently and continuously until it thickens, then stir more quickly until it nearly boils.
Remove from heat immediately to prevent curdling.
Pour into a bowl and stir until nearly cold.
Gradually add ⅓ cup of brandy and 2 ounces of blanched almonds, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set when gently heated, giving it body and richness.
- Milk
- Forms the liquid base and, with the yolks, gives the custard its smooth texture.
- White sugar
- Sweetens the custard and balances the richness of the yolks.
The step that matters
Stir the custard over boiling water and remove it from heat promptly. Egg yolks set when heated, so the custard can curdle if it gets too hot or is overheated. Gentle, constant stirring spreads heat evenly, and removing it as soon as it nearly boils keeps it smooth.
Swap the almond
The recipe marks almond as optional. How well each one fits the dish's main ingredients (milk, lemon, sugar, egg, brandy):
- Almondthe original
- Walnutfits about as well
- Chestnutfits less well
- Pistachiofits less well
Fit is the average pairing score against milk, lemon, sugar, egg, brandy. Candidates are from the same food group and used in at least 100 recipes.
