Why it works: Arrowroot and almond match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 179 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter until creamy.
Gradually stir in the sugar and arrowroot while beating the mixture.
Whisk the egg whites to a stiff froth and add them to the mixture.
Beat well for 20 minutes.
Bake
Pour into a buttered mold or tin.
Bake in a moderate oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Provides the starchy structure and a tender, delicate crumb.
- Butter
- Adds richness and moisture, and carries flavor through the batter.
- Egg whites
- Whisked to a stiff froth, they trap air that lifts and lightens the cake.
- Powdered white sugar
- Sweetens the cake and helps the butter cream to a smooth, light base.
The step that matters
Whisking the egg whites to a stiff froth. Egg whites hold air only when whisked to a stiff froth without deflating. Folding them in gently keeps that trapped air, which is what lifts this cake without any raising agent.

Fit is the average pairing score against sugar, butter, egg, almond. Candidates are from the same food group and used in at least 100 recipes.
