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 and bake
Mix all the ingredients together until smooth.
Pour the mixture into little cups, filling them half full.
Bake for 30 minutes until the puffs are golden brown.
Finish and serve
Remove from the oven, turn out onto a flat dish.
Rub 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 set the puffs as they bake.
- Flour
- Gives the batter body so the puffs hold their shape while rising.
- Milk
- Supplies moisture that turns to steam in the oven, helping the puffs rise.
- Butter
- Adds richness and flavor, and helps the outside brown.
The step that matters
Filling the cups half full. The batter needs room to rise in the hot oven. Overfilling can make the puffs spill over, while underfilling gives smaller, flatter results.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, egg, milk, butter, sugar):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, egg, milk, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
