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

Oven, in the book's wordsA moderate oven

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.

Make the batter

  1. Beat the butter to a cream.

  2. Beat the yolks and whites of the eggs separately for a long time.

  3. Add the sugar, rubbed through a sieve, and the grated lemon peel.

  4. Beat all together well for one hour.

Bake

  1. Bake in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Creamed with sugar to trap air and give the cake a tender, rich crumb.
Arrowroot
Provides the main starch structure and gives the cake a light, fine texture.
Sugar
Sweetens the cake and helps hold air when beaten into the butter.
Eggs
Add structure and lift through separately beaten whites and yolks, plus richness from the yolks.

The step that matters

Beating the eggs separately. Whites beaten until foamy trap air that leavens the batter, so they must be whipped well before being folded in. Under-beaten whites leave the cake dense and heavy.

Swap the arrowroot

How well each one fits the dish's main ingredients (butter, sugar, egg, lemon):

  1. Asparagusfits better
  2. Leekfits about as well
  3. Shallotfits about as well
  4. Arrowrootthe original

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