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

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

  2. Line a flat baking sheet with buttered parchment paper.

Make and bake

  1. In a bowl, mix the grated coconut, sugar, and egg whites until well combined.

  2. Using a fork, drop spoonfuls of the mixture onto the prepared baking sheet.

  3. Bake for 30 minutes or until lightly golden.

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

What each ingredient does

Grated coconut
Provides the bulk and chewy texture of the cookie, along with its coconut flavor.
Sugar
Sweetens the cakes and helps them brown lightly in the oven.
Egg whites
Bind the coconut and sugar together and help the cakes hold their shape while baking.

The step that matters

Baking until lightly golden. Sugar browns as it heats, so pulling the cakes too early leaves them pale and soft, while leaving them too long dries the coconut and darkens the sugar. Watch the color rather than relying only on the timer.

Swap the coconut

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

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Coconutthe original

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