Why it works: Butter and milk 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 ↓
Barley Custard Pudding
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.
Make the custard
Boil the milk.
Mix the barley with the sugar and a little cold milk.
Pour the hot milk over the barley mixture and return to the heat.
Add the butter and a small pinch of salt, stirring until it boils.
Remove from heat and add the yolk of the egg.
Whisk the egg white to a stiff froth and fold it into the mixture once it has cooled slightly.
Bake and serve
Butter a small pie dish and pour in the custard.
Grate a little nutmeg on top and bake for 10 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Patent barley
- Thickens the milk as it cooks, giving the pudding its body and set.
- Egg
- Yolk enriches and thickens the custard, while the whisked white adds lightness and airy texture.
- Butter
- Adds richness and a smooth, silky mouthfeel to the custard.
- Milk
- Forms the liquid base that the barley swells in and sets into a custard.
- Castor sugar
- Sweetens the pudding and helps soften the barley as it cooks.
The step that matters
Folding in the egg white. The white must be whisked to a stiff froth and folded in only after the mixture has cooled slightly. If it is too hot, the foam collapses and the pudding loses its lightness; overmixing also deflates the air that gives the texture.
Swap the nutmeg
How well each one fits the dish's main ingredients (barley, sugar, butter, milk, egg):
- Cinnamonfits better
- Nutmegthe original
- Parsleyfits less well
- Capersfits less well
Fit is the average pairing score against barley, sugar, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
