Why it works: Barley and arrowroot share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 36 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Barley Cream
Ingredients
Directions
Prepare the barley
Boil the barley in milk and water until tender, then strain the liquid.
Make the cream
In a saucepan, combine the strained barley with the cream and bring to a boil.
In a bowl, beat the egg yolk and egg whites with the arrowroot until well mixed.
Stir the egg mixture into the boiling cream, stirring until it thickens.
Remove from heat and mix in the loaf sugar and brandy or ratafia.
Serve
Pour the mixture into a bowl or cups and let it cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped with arrowroot, they add lightness and help the cream set as it thickens.
- Egg yolk
- Thickens the cream as it heats and adds richness and a smooth, custard-like body.
- Arrowroot
- Thickens the cream into a smooth, glossy texture without making it cloudy.
- Cream
- Provides fat for a rich, velvety mouthfeel.
- Barley
- Adds body and a mild, nutty flavour to the cream.
- Loaf sugar
- Sweetens the cream and balances its richness.
The step that matters
Stirring the egg mixture into the boiling cream. Egg proteins can scramble if they meet very hot liquid without enough stirring. Keep stirring steadily as it thickens so the mixture sets smooth rather than curdled.
