Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Beat the egg whites until stiff peaks form.
Gently fold in the powdered sugar and chopped nuts.
Bake
Drop by teaspoonfuls onto buttered baking sheets.
Bake in a slow oven at 300°F (150°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into stiff peaks, they trap air that gives the cakes their light, airy structure.
- Powdered sugar
- Dissolves readily into the whipped whites, adding sweetness and helping the cakes set smoothly.
- Nuts
- Add body, texture and nutty flavour to the cakes.
The step that matters
Folding in the powdered sugar and nuts. Overmixing or stirring vigorously knocks air out of the whipped egg whites, so the cakes spread flat and turn dense instead of staying light.
Swap the nuts
How well each one fits the dish's main ingredients (egg, sugar):
- Pecansfits better
- Almondfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
“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.
