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.
Make the dough
Mix the sugar, melted butter and lard, flour, rolled oats, raisins or currants, baking soda, mixed spices, sweet milk, and eggs together until well combined.
Bake
Drop a teaspoonful of the mixture onto a buttered baking pan, leaving space between each.
Bake in a preheated oven at 350°F (175°C) until golden.

Butter and flour 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
- Eggs
- Bind the dough and add structure as the cookies set in the oven.
- Butter and lard
- Add fat for tenderness and richness, and help the cookies brown.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Rolled oats
- Add chewy texture and a hearty, nutty bite to the cookies.
- Sugar
- Adds sweetness and helps the cookies brown and crisp at the edges.
- Baking soda
- Reacts with the mixture to help the cookies rise and spread lightly.
The step that matters
Leaving space between each drop. Cookies spread as they bake, so crowding the pan can make them merge and bake unevenly. Spacing lets each cookie set and brown on its own.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, flour, oats, milk, egg):
- Vanillafits better
- Raisinthe original
- Blueberryfits less well
- Figfits less well
Fit is the average pairing score against sugar, butter, flour, oats, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
