Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Cup Custard
Ingredients
Directions
Mix the custard
Beat the eggs together until well mixed.
Add the sugar to the eggs and mix well.
Combine the egg mixture with the milk and vanilla.
Bake in water
Pour the mixture into cups and place them in a pan of boiling water, ensuring the water does not bubble over the cups.
Watch carefully until the custard is set.
Cool
Remove the cups and place them in cold water to stop the cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated, giving the custard its firm, sliceable structure.
- Milk
- Provides the liquid base and moisture that keeps the custard tender.
- Sugar
- Adds sweetness and balances the savory taste of the eggs and milk.
The step that matters
Watch the custard as it sets in the water bath. Egg proteins set with gentle heat, and too much heat makes the custard curdle, weep or turn rubbery. Keeping the water below a bubbling boil and removing the cups once set prevents overcooking.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
