Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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. Sift together the flour, baking powder, baking soda, and salt.

  2. Add the bran and mix well.

  3. Incorporate the butter until evenly mixed with the dry ingredients.

  4. Stir in the nuts and raisins.

  5. Pour in the sour milk and mix quickly.

Shape and bake

  1. Scrape the dough onto a floured board and knead lightly.

  2. Roll out the dough and cut into biscuit shapes.

  3. Bake in a hot oven at 400°F (200°C) until golden.

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.

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
Provides the structure that holds the biscuits together as they bake.
Baking powder
Releases gas when moistened and heated, helping the biscuits rise.
Baking soda
Reacts with the sour milk's acidity to produce gas and aid rising.
Sour milk
Its acidity activates the baking soda and adds tenderness and tang.
Butter
Coats flour particles and adds fat for a tender, flaky crumb.
Raisins
Add sweetness and moisture to the dough.

The step that matters

Pour in the sour milk and mix quickly.. Once the liquid meets the baking soda and baking powder, gas starts forming right away. Mixing quickly and gently keeps that gas in the dough and avoids overworking the gluten, which would toughen the biscuits.

Swap the nuts

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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