Why it works: Flour and caraway match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,435 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Threadneedle Street Biscuits

Oven, in the book's wordsA very slow oven

Ingredients

Directions

The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Mix the flour and butter until crumbly.

  2. Add the sugar and mix well.

  3. Gradually add milk to form a smooth paste.

  4. Beat the mixture with a rolling pin until very smooth.

Shape and bake

  1. Roll out to ⅓ inch thick and cut with a small square cutter.

  2. Bake in a slow oven at 300°F (150°C) until crisp throughout.

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.

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

What each ingredient does

Flour
Provides the structure that holds the biscuits together as they bake.
Butter
Adds fat that makes the biscuits tender and rich in flavour.
Sugar
Adds sweetness and contributes to browning during baking.
Milk
Moistens the flour so the mixture can be worked into a smooth dough.

The step that matters

Bake in a slow oven until crisp throughout. Baking at a low temperature dries the biscuits gradually, so they become crisp through to the centre rather than browning on the outside while staying soft inside.

Swap the caraway

The recipe marks caraway as optional. How well each one fits the dish's main ingredients (flour, butter, sugar, milk):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits about as well
  4. Carawaythe original

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