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 rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Combine hot water and butter in a saucepan.
Heat until boiling.
Add flour all at once.
Stir quickly until the dough forms a ball that leaves the pan.
Set aside to cool slightly.
Add eggs one at a time.
Beat continuously while adding eggs.
After adding the last egg, beat vigorously.
Beat vigorously for 5 minutes.
Shape and bake
Drop tablespoonfuls onto buttered baking sheets.
Space the dough pieces 2 inches apart.
Bake in a preheated oven at 400°F (200°C) for 20 to 25 minutes, avoiding scorching.
Open and fill
Once cooled, make a small opening in one side with a sharp knife.

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
- All-purpose flour
- Starch and gluten form the structure that holds the puffed shell.
- Eggs
- Add moisture and protein that set the shell and lift it as steam expands.
- Butter
- Fat that tenderises the shell and adds richness.
The step that matters
Adding the eggs and beating the dough. The dough must be smooth and thick enough to hold its shape. Eggs added too quickly or too much liquid make the dough loose, so it spreads flat instead of puffing. Beating in each egg fully lets the dough absorb it evenly.
“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.
