Why it works: Arrowroot and milk work together. They rank in the top 18% of all ingredient pairs, and cooks put them together in 817 recipes. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓
Arrowroot Souffle
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the base
Mix the arrowroot smoothly with a little cold milk.
Boil the remaining milk with the flavoring ingredient and let it infuse for 10 minutes.
Strain the infused milk onto the arrowroot, stirring briskly.
Return the mixture to the saucepan and simmer gently for about 10 minutes.
Finish and bake
Add the sugar and beat each egg yolk into the mixture.
Stir in the stiffly whisked egg whites.
Pour the preparation into a well-buttered baking dish.
Bake in a hot oven at 400°F (200°C) for 25 to 30 minutes.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
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, stable base as it heats.
- Eggs
- Yolks enrich and thicken the base; whipped whites give the soufflé its lift and airy structure.
- Sugar
- Adds sweetness and softens the flavor of the custard base.
- Milk
- Forms the liquid base that the arrowroot thickens into a custard.
The step that matters
Stir in the stiffly whisked egg whites. Whites hold air that makes the soufflé rise. Stirring too hard or too long deflates the foam, so the bake comes out dense and flat.
Swap the arrowroot
How well each one fits the dish's main ingredients (sugar, egg, milk):
- Sweet potatofits better
- Capsicumfits better
- Asparagusfits better
- Arrowrootthe original
Fit is the average pairing score against sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
