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 ↓

Scotch Cookies

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.

Make the batter

  1. Cream the lard with the sugar.

  2. Add the beaten eggs and sour milk to the mixture.

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

  4. Add the rolled oats and chopped raisins to the dry ingredients.

  5. Combine the dry mixture with the wet mixture.

Bake

  1. Drop spoonfuls of the batter 1 inch apart on a greased baking sheet.

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

Flour and milk barely smell alike, yet cooks put them together in 78,219 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

Lard
Provides fat that makes the cookies tender and short.
Eggs
Bind the batter and add structure as the cookies set.
Sour milk
Adds moisture and acidity that reacts with the baking soda.
Baking soda
Reacts with the sour milk to produce gas, helping the cookies rise.
Rolled oats
Give the cookies a chewy texture and hearty body.
Sugar
Sweetens the cookies and helps them brown as they bake.
