Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

National Cake

Oven, in the book's wordsA moderate oven

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 the batters

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

  2. In a bowl, cream together 1 cup white sugar and ½ cup butter.

  3. Add ½ cup sweet milk, the beaten egg whites, ½ cup corn starch, and 1 cup flour mixed with 1 teaspoon cream of tartar and ½ teaspoon baking soda.

  4. Flavor with lemon extract.

  5. For the blue part, cream together 1 cup blue sugar sand and ½ cup butter.

  6. Add ½ cup sweet milk, the beaten egg whites, and 2 cups flour mixed with 1 teaspoon cream of tartar and ½ teaspoon baking soda.

  7. For the red part, cream together 1 cup red sugar and ½ cup butter.

  8. Add ½ cup sweet milk, the beaten egg whites, and 2 cups flour mixed with 1 teaspoon cream of tartar and ½ teaspoon baking soda.

Layer and bake

  1. In a cake pan, layer the red, then the white, and finally the blue batter.

  2. Bake in the preheated oven until a toothpick inserted comes out clean.

The flavor team

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
Creams with sugar to trap air and give the cake a tender, rich crumb.
Egg whites
Add structure and lift as they set in the oven, helping the cake hold its shape.
Flour
Forms the main structure of the cake as its proteins set during baking.
Cream of tartar and baking soda
React together to produce gas that helps the batter rise.
White sugar
Adds sweetness and helps tenderize the crumb when creamed with butter.

The step that matters

Layering the red, white, and blue batters. Each batter is separate and thick, so layering them carefully in the pan keeps the colors distinct. Pouring or spreading them unevenly can blend the colors during baking.

Swap the lemon

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

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