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
Preheat the oven to 400°F (200°C).
Beat the eggs well in a bowl.
Make the batter
Mix all the ingredients together until smooth.
Beat the mixture again just before pouring it into little cups, filling them half full.
Bake and serve
Bake for 1 hour until the puffs are golden brown.
Turn the puffs out onto a flat dish.
Spread a little butter over each puff and dust with powdered sugar.

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
- Provide structure and liquid that set the batter as it bakes.
- Flour
- Gives the batter body and structure so the puffs hold their shape.
- Milk
- Adds moisture that turns to steam, helping the puffs rise.
- Melted butter
- Adds fat for richness and helps the puffs brown and taste rich.
The step that matters
Beat the mixture again just before pouring. Batter left to stand lets the flour settle and air escape, so beating again just before pouring restores air and an even texture, helping the puffs rise evenly.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, egg, milk, butter):
- Nutmegthe original
- Cinnamonfits about as well
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against flour, egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
