Fairy Wafers

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the wafers

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

  2. In a bowl, mix the butter and sugar until creamy. Add the egg whites and milk, and mix well.

  3. Gradually add the flour and baking powder, stirring until combined.

  4. Drop teaspoonfuls of the mixture onto a greased baking sheet.

Top and bake

  1. In a separate bowl, combine the sugar, water, and egg white, then fold in the raisins and hickory nuts.

  2. Spoon this mixture on top of the wafers.

  3. Bake until lightly golden, being careful not to burn.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Butter
Creams with the sugar to add richness and a tender crumb.
Egg whites
Add structure and moisture, helping the batter bind and set when baked.
Flour
Provides the main structure that holds the wafers together as they bake.
Baking powder
Releases gas during baking so the wafers rise and stay light.
Sugar
Sweetens the wafers and promotes gentle browning in the oven.

The step that matters

Bake until lightly golden, being careful not to burn. Sugar browns quickly and then darkens and turns bitter once it passes golden, so the wafers need close watching near the end of baking.

Swap the nuts

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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