Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Line a cake tin with well-buttered paper.
Make the batter
Beat the butter and sugar together until creamy.
Dissolve the baking soda in the milk.
Add the eggs and milk to the butter and sugar mixture.
Mix the cream of tartar into the flour.
Combine the dry mixture with the wet ingredients.
Stir in the blanched almonds.
Bake
Pour the batter into the prepared tin.
Bake until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that sets the cake's crumb as the batter bakes.
- Butter
- Adds fat and richness, giving the batter a tender texture.
- Sugar
- Sweetens the cake and helps create a creamy, aerated batter when beaten with butter.
- Eggs
- Add structure and moisture, and help bind the batter as it sets.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to help the cake rise.
- Baking soda
- Reacts with the acid in the batter to produce gas that lightens the crumb.
The step that matters
Beat the butter and sugar until creamy. Beating creates tiny air pockets in the fat that expand in the oven, so the cake rises and turns out light. Under-beaten butter and sugar give a dense, heavy cake.
