Why it works: Almond and flour 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 ↓
Bourbon 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.
Prepare
Beat the yolks and whites of 5 eggs separately.
Grate and sift 1 pound of loaf sugar and the peel of 2 bitter oranges.
Blanch and pound ½ pound of sweet almonds with a little rose water.
Mix and bake
Whisk all these ingredients together for 30 minutes.
Mix in ½ pound of dried and sifted flour.
Pour the mixture into a hoop about 3 inches deep.
Bake in a moderate oven at 350°F (175°C) for 1 hour and 15 minutes.
Finish
Ice the top and sides of the cake immediately after removing it from the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked and separated yolks and whites provide structure and lift to the batter.
- Loaf sugar
- Adds sweetness and helps the batter hold air when whisked.
- Sweet almonds
- Add richness, fat and a tender, moist crumb.
- Dried flour
- Forms the starch structure that sets the cake as it bakes.
- Bitter orange peel
- Adds aromatic oils that flavour the batter.
The step that matters
Whisk the mixture for 30 minutes. Long whisking traps air in the eggs and sugar, which gives the cake its lift. Flour should be folded in gently afterward so the air is not knocked out before the cake bakes.
Swap the bitter orange
How well each one fits the dish's main ingredients (egg, sugar, almond, flour, rose, butter, rice):

Fit is the average pairing score against egg, sugar, almond, flour, rose, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
