Why it works: Flour and arrowroot match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 525 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Mix the flour and arrowroot together.
Beat the butter until creamy, then add the powdered sugar.
Make the batter
Stir in the flour, arrowroot, candied peel, and whisked eggs.
Beat the mixture until smooth and light.
Pour into a shallow dish lined with buttered paper.
Bake
Bake in a moderate oven (350°F / 175°C) for about an hour or more.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Flour
- Provides the main structure that holds the cake together as it sets.
- Arrowroot
- Adds a light, tender texture because it contributes starch without much gluten.
- Butter
- Adds richness and fat that makes the crumb tender and moist.
- Eggs
- Bind the batter and help it set, adding structure and lift when beaten.
- Powdered sugar
- Sweetens the batter and dissolves easily into the creamed butter.
The step that matters
Beat the mixture until smooth and light. Beating creams the butter and sugar and traps air in the batter, which gives the cake its lift and a fine, even crumb once baked.

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