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.

Make the batter

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

  2. In a bowl, mix the butter and sugar until creamy.

  3. Add the egg whites (or whole eggs) and milk, and mix well.

  4. Stir in the flour and baking powder until combined.

Shape and bake

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

  2. Sprinkle raisins and hickory nuts on top of each drop.

  3. Bake quickly, but do not 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.

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

What each ingredient does

Butter
Adds richness and tenderness, and helps the batter cream with the sugar.
Sugar
Sweetens the wafers and helps browning at the edges.
Egg whites
Provide structure and lift as the drops set in the oven.
Flour
Forms the structure that holds each wafer together as it bakes.
Baking powder
Releases gas in the oven so the wafers rise and turn light.

The step that matters

Bake quickly, but do not burn. Thin drops of batter brown fast, so a hot oven and close watching are needed. Sugar darkens quickly, and past that point the wafers turn bitter while staying underbaked inside is also a risk.

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.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
