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
Boil water and butter together.
Slowly add flour while boiling to avoid lumps.
Stir thoroughly and let cool.
Add beaten eggs and dissolved baking soda.
Bake and serve
Drop mixture onto a buttered pan, size of a walnut, three inches apart.
Bake at 400°F (200°C) for over 20 minutes without opening the oven for the first 10 minutes.
If the oven is too hot, reduce the heat instead of opening the door.
Let the puffs cool completely before cutting them open with scissors and filling with mock cream.

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
- Eggs
- Provide structure and leaning, so the puffs rise and set into hollow shells.
- Butter
- Adds fat and richness, and softens the dough for a tender texture.
- All-purpose flour
- Forms the starch and gluten framework that holds the puffs' shape.
- Water
- Creates the steam that lifts the dough and expands the puffs in the oven.
- Baking soda
- Helps the puffs rise and brown during baking.
The step that matters
Do not open the oven during the first 10 minutes of baking. Opening the door early lets steam and heat escape before the walls set, so the puffs can collapse instead of rising into hollow shells.
“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.
