Soda Cake

Why it works: Flour and caraway match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,435 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

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

Make the batter

  1. In a bowl, cream the butter or dripping with the flour.

  2. Add salt, mixed spice, caraway seeds or currants, and sugar; mix thoroughly.

  3. Dissolve baking soda in milk and add it along with vinegar to the mixture.

Bake

  1. Turn the batter into a greased tin lined with paper.

  2. Bake in the preheated oven until golden brown.

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

Flour
Forms the structure of the cake as the batter sets in the oven.
Butter or clarified dripping
Creamed with the flour to add richness and a tender crumb.
Baking soda
Reacts with the vinegar to produce gas that lifts the batter as it bakes.
Vinegar
Acidifies the batter so it reacts with the baking soda to make the cake rise.
Moist sugar
Adds sweetness and moisture, and helps browning in the oven.

The step that matters

Dissolve baking soda in milk and add it along with vinegar to the mixture.. Baking soda and vinegar react quickly to release carbon dioxide, so the batter should be baked promptly after mixing to keep the gas bubbles that give the cake its lift.

Swap the caraway

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits about as well
  4. Carawaythe original

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