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 ↓
Caramel Custard
Ingredients
Directions
Prepare the mold
Butter a plain tin pudding mold.
In a small saucepan, heat ½ cup sugar until it turns brown like coffee, then pour it into the mold, coating the bottom.
Make the custard
Beat the eggs and sugar together until well mixed, then add the milk and lemon essence.
Pour the mixture into the prepared mold and cover with buttered paper.
Steam and serve
In a large saucepan, add 1 inch of boiling water and place a saucer at the bottom.
Set the pudding mold on the saucer and cover the pan with a lid.
Steam slowly for at least 1 hour without boiling.
Turn out and 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
- Eggs
- Set the custard into a firm, sliceable structure as they cook.
- Milk
- Provides the liquid base and softness that makes the custard tender.
- Sugar
- Sweetens the custard and, caramelised, forms the brown syrup coating the mold.
The step that matters
Steaming without boiling. If the water boils hard, the steam and bubbling can make the custard full of holes or rough in texture. Gentle, steady steam cooks the egg proteins evenly so the custard stays smooth and set.
Swap the lemon
How well each one fits the dish's main ingredients (egg, milk, sugar):
- Vanillafits better
- Figfits about as well
- Raisinfits about as well
- Lemonthe original
Fit is the average pairing score against egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
