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 Cake
Ingredients
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.
Prepare
Preheat the oven to 350°F (175°C).
Cream the butter until smooth.
Make the batter
Beat the egg yolks and whites separately until fluffy.
Sift the sugar and add it to the egg yolks along with the grated lemon zest.
Combine all ingredients and mix well for 1 hour.
Bake
Pour the batter into a greased cake pan and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender, moist crumb.
- Arrowroot
- Provides the starch that sets during baking, forming the cake's structure.
- Eggs
- Whites trap air for lift, while yolks add richness and help bind the batter.
- Sugar
- Sweetens the cake and helps it brown during baking.
- Lemon zest
- Adds bright citrus aroma to the cake.
The step that matters
Beat the egg whites until fluffy before combining. Whipped whites hold air bubbles that expand in the oven and lift the batter. If they are under-beaten or deflated during mixing, the cake bakes up dense and flat.
