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 ↓
Oatmeal Cookies
Ingredients
Directions
The book says “a moderately quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, stir together the buttermilk, shortening, sugar, eggs, and baking soda until well combined.
Add the flour, raw oatmeal, raisins or currants, spices, and salt. Mix until fully incorporated.
Bake and serve
Drop tablespoonfuls of the mixture onto a greased baking sheet, spacing them three inches apart.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Adds moisture and acidity that reacts with the baking soda to help the cookies rise.
- Shortening
- Provides fat that gives the cookies a tender texture.
- Sugar
- Sweetens the cookies and helps them brown during baking.
- Eggs
- Bind the dough and add structure as the cookies set.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that leavens the cookies.
- Flour
- Provides the structure that holds the cookies together as they bake.
The step that matters
Spacing the dropped cookies. Cookies spread as the fat melts and the leavening works in the oven. Spacing them three inches apart keeps them from merging into one sheet and lets heat reach each cookie evenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
