Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
French Pancake
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.
Make the batter
In a bowl, stir the egg yolks with the salt and flour until smooth.
Gradually add the cold water and mix well.
Fold in the beaten egg whites gently.
Cook and bake
Heat a pan and add the butter; let it melt.
Pour in the pancake batter and cook slowly and evenly on one side.
Finish baking in the oven at 350°F (175°C) until set.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Yolks thicken and enrich the batter, while whipped whites add lift and a light, airy texture.
- Flour
- Provides structure so the batter sets into a sturdy pancake once cooked.
- Cold water
- Thins the batter to a pourable consistency, adding moisture that turns to steam while cooking.
- Butter
- Greases the pan and adds richness and flavor, helping the pancake brown gently.
The step that matters
Fold in the beaten egg whites gently. Egg whites hold air only when whipped; vigorous stirring deflates them, losing the lift that makes the pancake light and airy.
“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.
