Why it works: Butter and flour 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 ↓
Cream 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.
Make the dough
In a saucepan, melt the butter in the water.
Stir in the flour and baking soda until combined.
Let the mixture cool.
Beat the eggs and stir them into the mixture.
Drop small tablespoonfuls onto a dripping pan.
Bake and fill
Bake in a hot oven at 400°F (200°C) until golden.
Once baked, cut each puff in half with scissors.
Fill with thick boiled custard and reassemble the halves.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Butter
- Melts into the water to add fat and richness to the dough.
- All-purpose flour
- Provides the starch and gluten that give the dough its structure.
- Eggs
- Add moisture and set during baking, helping the puffs rise and hold their shape.
- Baking soda
- Reacts to lift the dough and aid browning.
The step that matters
Let the mixture cool before adding the eggs. If the dough is still hot, the eggs can scramble or cook partly before mixing, and the batter may thin too much, so the puffs may not rise well. Cooling lets the eggs blend smoothly and keeps the batter thick enough to hold its shape.
“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.
