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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix the syrup, flour, brown sugar, salt, shortening, baking powder, and egg until well combined.
Stir in the raisins and rolled oats.
Bake
Drop the mixture by teaspoonfuls onto a greased baking sheet, placing them 1 inch apart.
Bake for about 15 minutes or until delicately browned.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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 cookies together as they bake.
- Baking powder
- Releases gas during baking, helping the drops rise and become light.
- Egg
- Binds the ingredients together and adds structure as it sets in the oven.
- Shortening
- Adds fat that tenderizes the texture and carries flavor through the batter.
- Syrup
- Adds sweetness and moisture, and helps the drops brown as they bake.
- Rolled oats
- Give the drops a chewy, hearty texture and absorb some of the batter's moisture.
The step that matters
Spacing the drops 1 inch apart. This batter spreads as it bakes, and the baking powder makes it rise. Drops placed too close can merge, change shape, and bake unevenly, so leaving room between them lets each one set separately.
Swap the raisin
How well each one fits the dish's main ingredients (syrup, flour, sugar, egg, oats):
- Vanillafits better
- Raisinthe original
- Blueberryfits less well
- Datesfits less well
Fit is the average pairing score against syrup, flour, sugar, egg, oats. Candidates are from the same food group and used in at least 100 recipes.
