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 ↓

Wafer Biscuits

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. In a basin, combine the butter, salt, and sugar.

  2. Pour boiling water over the mixture and stir until the butter melts.

  3. Add the flour and mix to form a stiff dough.

  4. Beat the dough well with a rolling pin.

Shape and bake

  1. Roll the dough very thin and cut into shapes.

  2. Bake in a 400°F (200°C) oven until pale brown.

    Shared aroma: guaiacol (smoky, sweet).

Flour and butter 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

Flour
Forms the stiff dough structure that holds the biscuits together as they bake.
Butter
Adds fat that makes the dough tender and short, and it melts into the mixture.
Sugar
Adds mild sweetness and helps the biscuits brown in the oven.

The step that matters

Roll the dough very thin. Thin dough dries out and crisps during baking, while thicker pieces stay soft and dense in the centre. Even thickness also helps the biscuits bake evenly.
