Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Weigh the eggs and use their weight in fine sugar.
Use ⅔ the weight of the eggs in all-purpose flour.
Make the batter
Beat the egg yolks with the flour.
In a separate bowl, beat the egg whites until very stiff.
Gradually mix the beaten egg whites with the yolk-flour mixture.
Beat all ingredients together for 40 minutes.
Bake
Bake in a preheated oven at 400°F (200°C) for about 1 hour and 10 minutes.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Whipped whites trap air for lift, and yolks add richness and structure.
- Fine sugar
- Adds sweetness and helps stabilize the whipped egg foam.
- All-purpose flour
- Provides the protein and starch that set the cake's structure as it bakes.
The step that matters
Beat the egg whites until very stiff. The whites' air foam provides most of the cake's rise. Under-whipped whites give a dense cake, and over-whipped whites turn grainy and collapse when mixed with the other ingredients.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
