Why it works: Coconut and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 3,467 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Cocoanut Rusks

Oven, in the book's wordsA very moderate oven

Ingredients

Directions

The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the dough

  1. Rub the butter into the flour.

  2. Add the baking powder, sugar, and coconut.

  3. Work in the beaten egg to form a very stiff paste.

Bake

  1. Place small pieces of the mixture on a greased baking sheet.

  2. Bake for 20-25 minutes until golden.

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

What each ingredient does

Flour
Forms the structure that holds the rusk together as it bakes.
Baking powder
Releases gas during baking, helping the rusks rise and lighten.
Sugar
Adds sweetness and helps the surface brown to a golden colour.
Egg
Binds the mixture and adds structure and moisture to the paste.
Desiccated coconut
Adds flavour and a slightly chewy texture to the rusks.
Butter or lard
Adds fat, which tenderises the crumb and carries flavour.

The step that matters

Work in the beaten egg to form a very stiff paste. The paste must be stiff so the pieces hold their shape on the sheet instead of spreading. Too much liquid makes the rusks flat and dense rather than crisp and light.

Swap the coconut

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits about as well
  4. Coconutthe original

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