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 Drops

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a buttered saucepan, combine arrowroot, butter, sugar, lemon rind, and egg.

  2. Warm the mixture over low heat, beating thoroughly until light and thick.

Bake and serve

  1. Drop walnut-sized pieces onto a buttered baking sheet.

  2. Bake for about 15 minutes until done, then lift off with a knife.

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

What each ingredient does

Arrowroot
Thickens the mixture and gives the drops a light, tender structure as it sets.
Butter
Adds fat for richness and a tender texture, and helps the drops brown lightly.
Egg
Adds structure and binding, and helps the mixture become light and thick when beaten.
Sugar
Adds sweetness and helps with browning on the baking sheet.

The step that matters

Beating until light and thick. Beating incorporates air and lets the egg and butter emulsify with the arrowroot, which gives the drops lift and an even texture. Under-beating leaves them dense and uneven.

Swap the arrowroot

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

  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, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
