Why it works: Flour and butter 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 ↓
Jam 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.
Prepare
Preheat the oven to 400°F (200°C).
Separate the egg yolks and whites, beating the whites until stiff.
Cream the butter and sugar together.
Strain the yolks into the butter and sugar mixture and beat well.
Make and bake the puffs
Gently fold in the beaten egg whites and then the flour last.
Drop large spoonfuls onto a baking tin, ensuring they are all the same size and do not touch.
Bake for 15 minutes.
Fill and serve
Cut each puff open, leaving about an inch uncut for a hinge.
Fill with jelly or jam and sprinkle with fine sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites are beaten to trap air, giving the puffs lift and a light, airy structure.
- Hecker's prepared flour
- Provides the starch and structure that sets the puffs as they bake.
- Butter
- Creamed with sugar to add richness and tenderness to the puffs.
- Sugar
- Creamed with butter to add sweetness and help create a tender crumb.
- Sweet jam or jelly
- Fills the opened puffs, adding sweetness and fruity flavour.
The step that matters
Folding in the egg whites. Beaten whites hold trapped air that gives lift. Folding gently keeps that air in; stirring or overmixing deflates the batter and produces flat, dense puffs.
