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 ↓
Orange Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter in a bowl.
Gradually beat in the granulated sugar.
Add the beaten yolks of the eggs, grated orange rind, and orange juice.
In another bowl, mix the pastry flour, cornstarch, and baking powder.
Stir the dry mixture into the wet mixture.
Fold in the stiffly beaten egg whites.
Bake
Sprinkle with chopped almonds if desired.
Bake in a moderate oven at 350°F (175°C) until done.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Adds fat that makes the crumb tender and rich in flavor.
- Egg yolks
- Add richness and emulsify the batter, helping it set into a tender structure.
- Egg whites
- Whipped to foam, they lift the batter and give the cake its airy structure.
- Pastry flour
- Provides the structure of the cake while staying tender because of its lower protein.
- Cornstarch
- Softens the crumb by diluting the flour's gluten, giving a finer, more delicate texture.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
The step that matters
Fold in the stiffly beaten egg whites. Folding gently keeps the air trapped in the whites. Stirring or overmixing deflates the batter, which leads to a dense, flat cake.
