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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the dough
In a large bowl, cream together the shortening and sugar.
Beat in the eggs one at a time.
Stir in the sour milk, baking powder, and cinnamon.
Mix in the oatmeal, flour, salt, currants, and raisins.
Bake
Drop spoonfuls of the mixture onto buttered baking sheets.
Bake for 12-15 minutes or until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shortening
- Adds fat that gives the cookies a tender, crumbly texture.
- Sugar
- Creams with the fat for sweetness and helps the cookies brown.
- Eggs
- Bind the dough and add structure and richness.
- Sour milk
- Adds moisture and acidity that reacts with the baking powder to lift the cookies.
- Baking powder
- Releases gas in the dough, helping the cookies rise and stay light.
- Flour
- Provides the structure that holds the oats and fruit together.
The step that matters
Bake until golden, not longer. Oat and sugar-rich cookies go from golden to dry and hard quickly. Pulling them once the edges turn golden keeps the centres soft and chewy as they cool.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, cinnamon, flour, raisin):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, milk, cinnamon, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
