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

Ingredients
Directions
Make the cake
Separate the whites of two eggs and set aside for frosting.
Whisk together five eggs, two cups of sugar, two cups of flour, two small teaspoonfuls of baking powder, a small pinch of salt, and one cup of water until smooth.
Bake in a slow oven for about three quarters of an hour.
Top and frost
While the cake is warm, pour grated pineapple over it.
Combine the reserved egg whites, two cups of sugar, and two thirds cup of water to make a boiled frosting.
Boil the sugar and water until it threads, then pour over the beaten whites, stirring continuously.

Flour and egg share little aroma chemistry, yet 106,462 recipes mention both: they likely 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
- Set the cake structure and enrich the crumb, and the whites form the frosting's foam.
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Sugar
- Sweetens the cake and helps keep the crumb tender and the frosting glossy.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Pineapple (in the method)
- Adds moisture and fruity acidity to the warm cake.
The step that matters
Boil the sugar and water until it threads, then pour over the beaten whites. The syrup must be hot and concentrated enough to cook the egg whites into a stable foam. Pouring it in a thin, steady stream while stirring continuously prevents the whites from scrambling or deflating.
“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.
