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
Make the caramel
Put the dry castor sugar into an enamelled saucepan and let it melt and turn a rich brown over the fire, stirring all the time.
When the sugar is melted and browned, stir into it about 2 tablespoonfuls of hot water and the juice of 1/2 lemon.
Pour the caramel into a mould or cake tin and let it run all round the sides of the tin.
Make the custard
Heat the milk near boiling point and add the vanilla and sugar.
Whip up the eggs and stir the hot milk carefully into them, so as not to curdle the eggs.
Pour the custard into the tin on the caramel.
Bake and serve
Stand the tin in a larger tin with hot water and place it in the oven.
Bake in a moderately hot oven for about 20 minutes or until the custard is set.
Allow it to get cold, turn out, and serve.
Alternative method
Make the custard as in the recipe for "Cup Custard."
Take 4 oz. of castor sugar and put it over a brisk fire in a small enamelled saucepan, stirring until quite melted and a rich brown.
Cautiously add 2 tablespoonfuls of boiling water, taking care not to be scalded by the spluttering sugar.
Gradually stir the caramel into the hot custard.
Let it cool, and serve in custard glasses.
Nutrition, whole recipe (rough)
Counts 4 of 5 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 4 portions
| Ingredient | Portion assumed | kcal |

| Milk | 1 cup (244ml) whole | 149 |
| Egg | 1 large egg (50g) | 78 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Lemon | juice of 1 lemon (48ml) | 12 |
| Water | not in our table | 0 |

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 as they cook, giving the custard its firm, sliceable structure.
- Milk
- Forms the liquid base, and its proteins help the custard set into a smooth, creamy body.
- Sugar
- Melts and browns into caramel, adding sweetness and a deep toasted flavour.
The step that matters
Stirring the hot milk into the eggs. Pour the hot milk in slowly while whisking, so the eggs warm gradually. Adding it too fast cooks the egg proteins into lumps, so the custard curdles and turns grainy.
Swap the lemon
How well each one fits the dish's main ingredients (milk, egg, sugar):
- Vanillafits better

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