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 ↓

Plain Fruit Cake

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the batter

  1. Preheat the oven to 300°F (150°C).

  2. In a large bowl, cream together the brown sugar and butter.

  3. Stir in the molasses and milk until well combined.

  4. In another bowl, mix the flour, cream of tartar, and baking soda.

  5. Gradually add the dry ingredients to the wet mixture, stirring until smooth.

  6. Fold in the chopped raisins and currants.

Bake

  1. Pour the batter into a greased cake pan.

  2. Bake in the preheated oven for about 1 hour or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Brown sugar
Adds sweetness and moisture, and helps the cake brown.
Butter
Creamed with sugar to trap air and add tenderness and richness.
Molasses
Adds dark color, moisture, and a deep, slightly acidic flavor.
Flour
Provides the structure that holds the cake together as it sets.
Eggs
Bind the batter and add structure, richness, and lift when baked.
Baking soda
Reacts with the acidic molasses to produce gas that helps the cake rise.

The step that matters

Gradually add the dry ingredients to the wet mixture. Adding dry ingredients slowly and stirring until smooth keeps the batter evenly combined and prevents lumps. Overmixing once flour is added can develop gluten and make the cake tough.

Swap the raisin

How well each one fits the dish's main ingredients (sugar, butter, molasses, milk, flour, egg, cream):

  1. Vanillafits about as well
  2. Raisinthe original
  3. Figfits less well
  4. Strawberryfits less well

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