Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Sift the baking soda, cream of tartar, and salt into the flour.
Stir in the sour cream and the well-beaten egg.
Bake
Drop the mixture into buttered pans.
Bake in a hot oven at 400°F (200°C) for 20 minutes.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Provides the main structure that holds the cakes together as they set.
- Sour cream
- Adds moisture and richness, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the acidic sour cream to release gas, helping the cakes rise.
- Cream of tartar
- Acts as an acid that works with the baking soda to leaven the batter.
- Egg
- Binds the batter and adds structure and richness as it sets in the oven.
The step that matters
Stir in the sour cream and egg, then bake promptly. Baking soda and the acids in the batter react as soon as they are wet, releasing gas. Delaying the bake lets that gas escape, so the cakes may rise less.
