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 ↓
Custard Pudding, Baked
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Put the milk, sugar, and lemon rind into a saucepan and let it infuse for about 30 minutes.
Whisk the eggs (yolks and whites) together.
Pour the infused milk into the eggs while stirring continuously.
Assemble
Prepare a pie dish lined with pre-baked pastry.
Strain the custard into the dish.
Grate a little nutmeg on top.
Bake
Bake in a slow oven at 300°F (150°C) for about 30 minutes or longer.

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
- Proteins set as they heat, thickening the milk into a firm, sliceable custard.
- Milk
- Provides the liquid base that gives the custard its body and soft texture.
- Sugar
- Adds sweetness and helps balance the richness of the eggs and milk.
- Lemon rind
- Infused into the milk to add a fresh citrus aroma.
The step that matters
Pour the infused milk into the eggs while stirring continuously. Adding hot milk to eggs gradually while stirring warms the eggs slowly. Without constant stirring, the eggs can partly scramble, leaving a lumpy rather than smooth custard.
Swap the lemon
How well each one fits the dish's main ingredients (milk, sugar, egg):

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