Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
German Puffs
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 sweet milk, flour, melted butter, and 3 egg yolks.
Fill buttered cups halfway with the mixture.
Bake and make the sauce
Bake for 20 minutes.
In another bowl, beat the reserved egg whites to stiff peaks.
Gradually add powdered sugar and orange juice, mixing until smooth.
Serve
Turn the baked puffs out onto a platter and cover with the sauce before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks enrich the batter, and whipped whites give the sauce its light, airy body.
- Flour
- Provides the structure that holds the puffs together as they rise and set.
- Sweet milk
- Supplies the liquid that turns the batter into a pourable mixture that steams and sets in the oven.
- Butter
- Adds richness and helps keep the puffs tender and golden.
- Powdered sugar
- Sweetens the sauce and helps it hold together smoothly with the orange juice.
- Orange juice
- Adds acidity and bright flavor to the sauce, balancing its sweetness.
The step that matters
Beating the reserved egg whites to stiff peaks. Whites that are under- or over-beaten won't hold air well, so the sauce loses its light texture or turns grainy. Adding the sugar gradually helps the whites stay stable.
Swap the orange
How well each one fits the dish's main ingredients (milk, flour, butter, egg, coffee, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against milk, flour, butter, egg, coffee, sugar. Candidates are from the same food group and used in at least 100 recipes.
