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 ↓
Dolly Varden Cake
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 dark batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together ½ cup butter and 1 cup sugar for the dark part.
Add 4 egg yolks, ⅓ cup milk, and ½ cup syrup, and mix well.
In another bowl, combine 2 cups flour, 2 teaspoons baking powder, 1 cup chopped raisins, ½ cup currants, 1 teaspoon cloves, 1 teaspoon cinnamon, and ¼ teaspoon nutmeg.
Gradually add the dry ingredients to the wet mixture and mix until combined.
In a separate bowl, combine 2 cups flour and 2 teaspoons baking powder.
Add the dry mixture to the wet mixture and mix until smooth.
Make the light batter
For the light part, cream together ½ cup butter and 1½ cups sugar.
Add 3 egg whites, ⅓ cup milk, and 2 teaspoons vanilla, mixing well.
Bake, layer and frost
Pour both mixtures into square tins.
Bake until a toothpick comes out clean.
Once cooled, layer the dark and light parts with jelly in between.
Beat the remaining egg white, then mix it with 1 cup powdered sugar.
Spread the frosting on top.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Butter
- Adds fat for a tender crumb and rich flavor.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Egg yolks
- Add richness and help emulsify the batter for a smooth, moist crumb.
- Egg whites
- Add structure and lightness to the light part of the cake.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
The step that matters
Mixing the batter after adding the dry ingredients. Once flour meets liquid, gluten begins to form. Mixing only until combined keeps the crumb tender, while overmixing makes the cake tough and dense.

Fit is the average pairing score against butter, milk, flour, sugar, syrup, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
