Why it works: Cinnamon and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓

Wafer Biscuits

Oven, in the book's wordsA very slack oven

Ingredients

Directions

The book says “a very slack oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

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

  2. Melt the sugar and mix it with the egg whites, flour, cinnamon, and cloves to form a liquid paste.

Shape and bake

  1. Butter copper plates lightly and drop the paste onto them in penny-sized drops, spaced four inches apart.

  2. Spread each drop with your finger to make them larger and about the thickness of wafers.

  3. Bake until they are a fine color.

  4. Optionally, roll them into little horns or use them to decorate cream.

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

What each ingredient does

Sugar
Melts to add sweetness and help the wafers set crisp as they cool.
Flour
Provides structure so the thin batter holds its shape while baking.
Whites of 2 eggs
Give the batter its liquid body and help bind and lift the thin wafers.

The step that matters

Spreading the drops. Drops must be spread evenly to the same thin thickness, because thin spots brown and burn quickly while thick spots stay soft and do not crisp.

Swap the clove

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

  1. Nutmegfits better
  2. Cardamomfits better
  3. Allspicefits about as well
  4. Clovethe original

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