Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Baked Custard in a Saucepan, with Burnt-Sugar Sauce
Ingredients
Directions
Prepare the custard
Whisk 6 eggs and 1 pint of milk together in a bowl and flavor to taste.
Make the caramel
Add a few lumps of white sugar and enough water to moisten it in a small enamel-lined saucepan.
Heat the saucepan on the stove until the sugar turns bright golden; remove it to prevent burning.
Once the sugar is brown, carefully add more water until it reaches a syrupy consistency.
Cook and serve
Swirl the saucepan to coat the sides with caramel, then pour in the custard mixture.
Cover the saucepan with a lid and place hot embers on top; cook gently for the same time as baking.
Serve the custard hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm, tender custard as they cook, giving the dish its structure.
- Milk
- Provides the liquid base that the eggs set in, keeping the custard soft and creamy.
- White sugar
- Melts and darkens into caramel, adding sweetness and a deep toasted flavor.
The step that matters
Heating the sugar to caramel. Sugar darkens quickly once it turns golden and can burn within moments, becoming bitter. Removing the pan from heat as soon as it reaches the right color stops the cooking and keeps the caramel tasting sweet rather than scorched.
Swap the apple
How well each one fits the dish's main ingredients (egg, milk, sugar, butter):
- Vanillafits better
- Figfits better
- Coconutfits about as well
- Applethe original
Fit is the average pairing score against egg, milk, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
