Why it works: Wheat and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,373 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Whole-Wheat Pop-Overs
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a bowl, mix the whole wheat flour, all-purpose flour, sugar, and salt.
Add the melted butter and the beaten egg yolks, mixing well.
In another bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Bake
Pour the batter into buttered stoneware cups, filling them halfway.
Bake for 20 minutes, then reduce the heat and bake for an additional 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air and lift the batter, while the yolks add richness and binding.
- Whole wheat flour
- Provides the main structure and a nutty, earthy flavor.
- All-purpose flour
- Adds gluten for structure, helping the popovers hold their rise.
- Butter
- Adds fat for tenderness and rich flavor.
- Sugar
- Adds mild sweetness and helps the crust brown.
The step that matters
Gently fold the egg whites into the batter. Whipped egg whites hold air that makes the popovers rise. Vigorous stirring deflates them, so the popovers bake flat and dense.
