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 ↓

Cup 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. 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 the batter

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

  2. In a large bowl, cream the butter and sugar together until light and fluffy.

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

  4. Dissolve the baking soda in the sweet milk and add it to the mixture.

  5. Sift the flour, cream of tartar, and salt together, then gradually add to the wet ingredients.

  6. Stir in the vanilla extract and mix until smooth.

  7. If desired, fold in raisins.

Bake

  1. Pour the batter into a greased cake pan and bake for about 30-40 minutes or until a toothpick comes out clean.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
Creams with sugar to trap air and add richness and tender texture.
Eggs
Provide structure and binding, and help the cake hold its rise.
All-purpose flour
Forms the main structure of the cake as its proteins set during baking.
Sugar
Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
Baking soda
Reacts with the acid in cream of tartar and milk to produce gas that makes the cake rise.
Cream of tartar
Acidic component that works with baking soda to leaven the batter and aid browning.

The step that matters

Dissolving the baking soda and combining the dry ingredients. Baking soda needs an acid to release carbon dioxide, so the leavening must be evenly distributed and combined promptly. Uneven mixing can leave pockets of soda that taste bitter or cause uneven rising.

Swap the raisin

The recipe marks raisin as optional. How well each one fits the dish's main ingredients (butter, egg, sugar, flour, milk, cream, vanilla):

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

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