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 ↓

Biscuits, Shortbread

Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Prepare the dough

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

  2. Rub the butter into the flour until finely mixed.

  3. Add the sugar and work together until a stiff dough forms.

  4. Turn the dough onto a floured board and knead until smooth.

  5. Roll out the dough to about ½ inch thick.

Shape and bake

  1. Cut into rounds with a crinkled pastry cutter.

  2. Place on a greased baking tin and bake until pale brown.

  3. Sprinkle each biscuit with castor sugar and cool on a cake tray.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The flavor team

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.

    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

Butter
Rubbed into the flour to add richness and a tender, crumbly texture.
Flour
Forms the structure of the dough that holds the biscuit shape.
Castor sugar
Adds sweetness and helps the biscuits brown lightly in the oven.

The step that matters

Working the dough until smooth. Kneading too little leaves the dough crumbly and hard to roll, while overworking develops gluten and makes the biscuits tough. Stop once the dough is smooth and cohesive.
