Why it works: Vanilla and sugar are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Potato Starch Angel 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.
Make the batter
Beat the egg whites until frothy, then add the cream of tartar and continue beating until stiff and flaky.
Gradually add the sugar while continuing to beat.
Fold in the potato starch mixed with salt, which has been sifted several times, and add the vanilla.
Bake and serve
Bake for 45 to 50 minutes in a 350°F (175°C) oven in an unbuttered angel cake pan.
If the cake begins to brown, cover it with a buttered paper.
When done, loosen the cake around the edge and turn it out immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam, they form the airy structure that lifts the cake as it bakes.
- Potato starch
- Forms a tender, light crumb with little gluten, giving a delicate texture.
- Sugar
- Stabilises the whipped whites and adds sweetness and a fine, moist crumb.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stable, stiff foam.
The step that matters
Folding in the potato starch. Folding gently keeps the air trapped in the beaten whites. Stirring or deflating the batter causes the cake to sink and turn dense.
Swap the potato
How well each one fits the dish's main ingredients (vanilla, egg, cream, sugar):
- Arrowrootfits better
- Sweet potatofits better
- Asparagusfits about as well
- Potatothe original
Fit is the average pairing score against vanilla, egg, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
