Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Boston Cream Puffs
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
In a saucepan, combine hot water and butter over medium heat until boiling.
Stir in flour and mix until smooth; remove from heat.
Allow to cool slightly, then beat in the eggs until well combined.
Bake and fill
Drop spoonfuls of the mixture onto greased baking sheets.
Brush the tops with egg white and bake at 400°F (200°C) for 10 to 15 minutes.
Once cooled, slice off the tops, fill with cream, and replace the tops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Starch that gelatinises with the liquid and sets the puff's hollow structure.
- Eggs
- Proteins set during baking and add richness and lift to the dough.
- Butter
- Fat that adds tenderness and flavour and melts into the boiling water.
- Hot water
- Liquid that gelatinises the flour and creates steam for rising.
The step that matters
Beating in the eggs after cooling slightly. If the mixture is too hot, the eggs can scramble, and if too cool, the dough will not become smooth and glossy. Gentle cooling keeps the eggs incorporated so the dough can expand and form hollow shells in the oven.
