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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Softens as it simmers, giving the cream body and a grainy, pleasantly chewy texture.
- Egg yolk and egg whites
- Thicken the cream as they set with heat, giving it a smooth, custard-like body.
- Arrowroot
- Starch that thickens the egg mixture and helps keep the cream smooth when heated.
- Cream
- Provides richness and fat, giving the dish a silky mouthfeel.
- Loaf sugar
- Adds sweetness and balances the richness of the cream and eggs.
The step that matters
Stir the egg mixture into the boiling cream until it thickens. Egg proteins set when heated, so if the cream is too hot or stirred poorly, the eggs can curdle or scramble. Adding them to the hot cream gradually, while stirring, keeps the custard smooth.
