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 ↓
Cup Custard
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
In a cup, combine the milk, salt, and nutmeg.
Butter another cup and pour the mixture into it.
Bake
Place the cup in a pan of boiling water, filling the pan to nearly the top of the cup.
Bake until the custard is set.
Chill and serve
Chill and serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that heats and sets into a soft custard.
- Nutmeg
- Adds a warm, aromatic flavour to the custard.
The step that matters
Setting the cup in boiling water. The water bath surrounds the custard with gentle, even heat. This slows the rise in temperature so the custard sets smoothly and evenly, rather than curdling, cracking, or turning rubbery at the edges.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, butter):
- Cinnamonfits better
- Nutmegthe original
- Parsleyfits less well
- Macefits less well
Fit is the average pairing score against milk, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
