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 ↓
White Fruit 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.
Prepare
Blanch and shred the almonds and slice the citron thin.
Make the batter
Cream the butter, gradually adding the flour mixed and sifted with baking soda, then add the lemon juice.
Beat the egg whites until stiff, gradually adding the sugar.
Combine the two mixtures and add the fruit and almond extract.
Bake
Bake in a deep pan at 350°F (175°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten until stiff, they trap air and give the cake its light, airy structure.
- Butter
- Creamed with the sugar, it adds richness and a tender crumb.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Sugar
- Adds sweetness and helps the egg whites hold their stiff, glossy form.
- Baking soda
- Reacts with the acid in the lemon juice to help the cake rise.
- Candied cherries
- Add sweetness, moisture and bright color to the finished cake.
The step that matters
Folding the egg whites into the batter. Stiff egg whites hold air that gives lift. Overmixing or deflating them makes the cake dense and heavy, so combine gently.
