Gingerbread-nuts

Oven, in the book's wordsA slow oven

Ingredients

Directions

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

Make the dough

  1. In a large bowl, mix together the flour, treacle, butter, sugar, candied peel, ginger, coriander, and caraway seeds until well combined.

  2. Stir in the carbonate of ammonia, using up to 4 ounces for a lighter texture.

Shape and bake

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

  2. Shape the mixture into small nuts and place them on a baking sheet.

  3. Bake for about 20 minutes or until golden brown.

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

What each ingredient does

All-purpose flour
Provides the structure that holds the dough together once shaped and baked.
Treacle (or molasses)
Adds moisture, deep sweetness and color, and helps the nuts brown.
Butter
Adds fat that softens the texture and gives a richer, tender bite.
Sugar
Sweetens the dough and promotes browning in the oven.
Carbonate of ammonia
Acts as a leavening agent that releases gas when heated, lightening the nuts.

The step that matters

Stirring in the carbonate of ammonia. This leavening agent breaks down into gas when heated, which lightens the nuts. It should be finely powdered and evenly mixed so it disperses well. Using too much leaves a sharp ammonia taste, so the stated amount matters.

Swap the coriander

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

  1. Cinnamonfits better
  2. Cardamomfits better
  3. Nutmegfits better
  4. Corianderthe original

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