Why it works: Flour and walnut are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
White-mountain Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Beat the egg yolks until thick.
Beat the egg whites until stiff peaks form.
Make and bake the cakes
Combine the flour and baking powder, then add to the yolks.
Gently fold in the egg whites.
Fill small cups or pans half full with the batter.
Place half an English walnut on top of each before baking.
Bake until golden, then frost over the nuts after removing from pans.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Egg whites
- Whipped to stiff peaks and folded in, they give the cakes their light, airy structure.
- Egg yolks
- Beaten thick, they add richness and help build the batter's body.
- All-purpose flour
- Provides the starch and gluten network that sets the cake's crumb as it bakes.
- Baking powder
- Releases gas in the batter so the cakes rise and turn tender in the oven.
The step that matters
Gently fold in the egg whites. Whipped egg whites hold air that gives the cakes their lift. Stirring vigorously or overmixing knocks that air out, leaving dense, flat cakes.
Swap the walnut
How well each one fits the dish's main ingredients (egg, flour):
- Almondfits better
- Milletfits better
- Macadamia nutfits better
- Walnutthe original
Fit is the average pairing score against egg, flour. 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.
