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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Boil 1 cup of hot water and ½ cup of butter together.
While boiling, stir in 1 cup of dry sifted flour.
Remove from heat and stir until it forms a thin paste.
Allow to cool, then stir in 3 eggs. Stir for 5 minutes.
Bake
Drop tablespoonfuls onto a buttered baking sheet.
Bake in a 400°F (200°C) oven for 25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the starch paste that gives the puffs their structure as it sets.
- Eggs
- Add moisture and structure, helping the dough puff and set during baking.
- Butter
- Adds fat and richness, softening the paste and contributing to tenderness.
The step that matters
Stir in the eggs after cooling. If the paste is still hot, the eggs can scramble, and the dough may be too loose to hold its shape or puff properly.
