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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs for one minute.
Add the sugar and beat for five minutes.
Mix in one cup of flour and beat for one more minute.
Add the water, remaining flour, and baking powder, then mix well.
Flavor with lemon or vanilla extract to taste.
Bake
Pour the batter into a baking pan and bake in a 350°F (175°C) oven for 25 to 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Trap air when beaten, giving the cake its light, airy structure.
- White sugar
- Sweetens the cake and helps hold air in the beaten eggs for a fine crumb.
- Flour
- Forms the cake's structure as it sets in the oven.
- Magic baking powder
- Releases gas in the batter so the cake rises during baking.
The step that matters
Beat the eggs and sugar fully before adding flour. Beating eggs and sugar incorporates air that forms the foam holding the batter up. Deflating it by overmixing or delaying the flour can leave the cake dense and flat.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, flour):

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