Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 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 the water in a pot.
Add the flour and stir briskly until fully cooked.
Break in the eggs one at a time, stirring each until smooth.
Add the powdered carbonate of ammonia and mix well.
Bake
Drop tablespoonfuls onto baking sheets.
Bake in a hot oven at 400°F (200°C) until golden.

Shared aroma: isobutyraldehyde (malty, green).
Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Flour
- Forms the starchy paste that sets into the hollow shell when baked.
- Eggs
- Add structure and moisture, and help the puffs rise and set.
- Carbonate of ammonia
- Releases gas in the oven to lift the dough and create the hollow interior.
- Water
- Turns the flour into a paste and creates steam that helps the puffs expand.
The step that matters
Cooking the flour into the water. Stirring the flour into boiling water gelatinizes its starch, forming a paste strong enough to hold its shape and trap steam. If it is not cooked through, the puffs may collapse or stay gummy.
“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.
