Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Oven, in the book's wordsA hot oven

Ingredients

Directions

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

Prepare

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

Make and shape the dough

  1. In a bowl, mix flour, butter, sour cream, salt, and baking soda until a soft dough forms.

  2. Roll the dough very thin on a floured surface.

  3. Cut out biscuits and place them on a baking sheet.

Bake

  1. Bake in the hot oven for about 5 minutes.

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: delta-dodecalactone (sweet, creamy).

    Shared aroma: isobutyraldehyde (malty, green).

    Shared aroma: acetaldehyde (pungent, ethereal).

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 structure of the dough as its proteins and starches set during baking.
Butter
Adds fat that tenderises the biscuit and helps it brown.
Sour cream
Adds moisture and acidity that keeps the biscuit tender and reacts with the baking soda.
Baking soda
Reacts with the acidity in sour cream to produce gas that lifts the dough.

The step that matters

Roll the dough very thin. Thin dough bakes quickly and evenly, so the biscuit crisps through rather than staying doughy in the centre. Uneven thickness leads to some pieces burning while others stay underdone.
