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 ↓
Almond Layer Cake
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
Preheat the oven to 350°F (175°C).
Cream the butter in a bowl, then gradually add the sugar.
Slowly mix in the milk, alternating with the flour.
Fold in the beaten egg whites.
Divide the batter into two pans.
Top and bake
Bake one pan plain.
Sprinkle the other pan with sliced almonds.
Dust the other pan with powdered sugar.
Bake both pans for 12 minutes.
Make the filling
For the filling, boil 1 cup of sugar with ½ cup of water.
Beat in the stiff egg white.
Add chopped almonds.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the cake's structure as its proteins set during baking.
- Baking powder
- Releases gas in the batter, lifting the layers as they bake.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Sweetens the cake and helps keep the crumb soft and moist.
- Egg whites
- Trap air when beaten, adding lightness and helping the cake set.
- Milk
- Adds moisture that hydrates the flour and dissolves the sugar.
The step that matters
Folding in the beaten egg whites. Stir them in gently with a spatula so the air bubbles they hold are not knocked out. Those bubbles are what make the layers light, and overmixing deflates them and produces a dense cake.
