Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients

Directions

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

Prepare the dough

  1. Melt the alum in the treacle.

  2. Rub the butter into the flour.

  3. Stir the melted alum into the treacle.

  4. Mix all ingredients together until stiff.

Shape and bake

  1. Roll out the dough thinly and mark with a mold.

  2. Place on buttered baking tins.

  3. Bake in a moderate oven at 350°F (175°C).

Finish

  1. Once baked, gloss with a mixture of butter, gum, and a dissolved egg.

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

What each ingredient does

Treacle
Provides sweetness, dark colour and moisture to the dough.
Flour
Forms the structure that holds the dough together once baked.
Butter
Adds fat, tenderness and richness, and is rubbed into the flour.
Alum
Acts as a raising agent that helps the dough puff and set.
Oat meal
Adds a coarser texture and body to the dough.

The step that matters

Mix all ingredients together until stiff. The dough must be stirred to a uniform, firm consistency so the flour is evenly hydrated and the roll bakes evenly rather than turning out patchy or sticky.

Swap the ginger

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

  1. Capersfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Gingerthe original

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