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
Prepare the syrup and dry ingredients
Boil the sugar and water until it reaches 237°F (113°C). Set aside to partially cool.
Sift the flour and baking powder together 5 times.
Mix the cream of tartar with 1 teaspoon of sugar on a piece of paper.
Make the batter
In a large bowl, beat the cold egg whites until stiff and white. Add the cream of tartar and continue to whip until stiff peaks form.
Pour the cooked syrup into the egg whites without scraping the pan and whip briskly.
Add the extract, then carefully fold in the flour and baking powder.
Bake and assemble
Bake in 2 deep ungreased layer cake pans, starting at 250°F (120°C) and finishing at 425°F (220°C).
Set the layers together with 'Jiffy Icing' an inch thick between and on top of the layers. Optionally, tint the icing pink or the cake dough.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam that gives the cake its light, airy structure.
- Granulated sugar
- Cooked into a syrup that sweetens and stabilises the whipped egg whites.
- Flour
- Folded in gently to add just enough structure to hold the airy foam.
- Cream of tartar
- Acidifies the egg whites, helping them whip to stable, fine-textured peaks.
- Baking powder
- Provides additional lift as the batter heats in the oven.
The step that matters
Folding in the flour. Flour must be folded gently so the whipped egg white foam keeps its air. Stirring or deflating it makes the cake dense and reduces its rise.
