Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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.
Make the batter
Break the eggs into a cup and fill it with sweet cream.
In a mixing bowl, combine the eggs and cream with sugar, flour, cream of tartar, baking soda, nutmeg, and salt. Mix until well combined.
Bake
Pour the batter into a greased baking pan.
Bake at 350°F (175°C) until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness to the batter as they set during baking.
- Flour
- Forms the structure of the cake as its proteins set in the oven.
- Sugar
- Adds sweetness and helps the cake brown while baking.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that makes the cake rise.
- Cream of tartar
- Acidifies the batter so the baking soda reacts and lifts the cake.
The step that matters
Mixing the batter with baking soda and cream of tartar. Baking soda and cream of tartar react as soon as they meet liquid, so the batter should be mixed well and baked promptly to keep the gas bubbles that give the cake its rise.
