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
Mix the barley smoothly with a little cold milk.
Boil the remaining milk and pour it over the barley, stirring continuously.
Add the butter, sugar, and a pinch of salt, then return to the heat and stir until it boils.
Cool slightly.
Beat in the egg yolk.
Fold in the stiffly whisked egg white.
Bake
Pour the mixture into a buttered pie dish.
Grate a little nutmeg on top.
Bake gently at 350°F (175°C) for 10 minutes.

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 a soft, set texture.
- Butter
- Adds richness and a smooth, tender mouthfeel to the pudding.
- Egg
- Enriches the custard and helps it set; the whisked white adds lightness.
- Milk
- Forms the liquid base that the barley thickens into a creamy custard.
- Castor sugar
- Adds sweetness and balances the savoury notes of the barley and butter.
The step that matters
Fold in the stiffly whisked egg white. Folding gently keeps the air in the egg white; overmixing deflates it, so the pudding loses the lightness the whisked white is meant to give.
Swap the nutmeg
How well each one fits the dish's main ingredients (barley, butter, sugar, egg, milk):
- Cinnamonfits better
- Nutmegthe original
- Parsleyfits less well
- Capersfits less well
Fit is the average pairing score against barley, butter, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
