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 ↓

Bread Cake Sponge

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. In a mixing bowl, cream the butter and sugar together until light and fluffy.

  2. Add the eggs one at a time, mixing well after each addition.

  3. Stir in the sponge.

  4. In a separate bowl, combine the flour and baking soda.

  5. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

  6. Fold in the raisins.

Bake

  1. Pour the batter into a greased baking pan and bake for 30-35 minutes or until a toothpick comes out clean.

Flour and butter 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
Creamed with sugar to trap air and add richness and tenderness.
Eggs
Add structure and bind the batter as they set in the oven.
Flour
Forms the main structure of the cake as its proteins set on baking.
Baking soda
Reacts with the batter to produce gas that helps the cake rise.
Sugar
Sweetens the batter and helps hold air when creamed with butter.

The step that matters

Mixing the dry ingredients into the wet mixture. Overmixing once the flour is added develops gluten, which can make the cake tough and dense. Mix only until just combined so the texture stays tender.
