Why it works: Arrowroot and lemon match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Arrowroot Creams
Ingredients
Directions
Mix the arrowroot with a little milk to form a smooth paste and add the egg yolk.
Boil the remaining milk with the powdered sugar, lemon peel, and cinnamon.
Pour the boiling milk mixture onto the arrowroot paste, stirring continuously until nearly cold.
Transfer the mixture into custard glasses and set aside.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the milk into a smooth custard as it cooks and cools.
- Egg yolk
- Adds richness and body to the custard.
- Milk
- Forms the liquid base that the arrowroot thickens.
- Powdered sugar
- Adds sweetness and dissolves easily into the hot milk.
The step that matters
Pour the boiling milk onto the paste while stirring. Adding hot milk to the starch and yolk mixture while stirring constantly keeps the starch dispersed and prevents lumps, while the yolk is blended in smoothly rather than scrambling.
Swap the arrowroot
How well each one fits the dish's main ingredients (sugar, egg, milk, lemon, cinnamon):
- Sweet potatofits about as well
- Arrowrootthe original
- Capsicumfits about as well
- Asparagusfits less well
Fit is the average pairing score against sugar, egg, milk, lemon, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
