Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Petits Choux Garnis
Ingredients
Directions
The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux paste
In a saucepan, melt the butter with the milk, sugar, and lemon peel over medium heat.
Once it boils, remove from heat and quickly stir in the flour until it forms a paste.
Return to heat and stir for 2 minutes.
Add the eggs one at a time, mixing well after each addition.
Stir in the salt and ratafia biscuits, then beat for 2 minutes.
Bake and fill
Drop spoonfuls onto a baking sheet and bake in a gentle oven at 300°F (150°C) until golden.
Once baked, cut each choux open and fill with your choice of sweetmeat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the starch paste that gives the choux its structure once baked.
- Eggs
- Add structure and lift, and help the paste puff as it bakes.
- Butter
- Adds richness and tenderness to the paste.
- Milk
- Provides the liquid that cooks with the flour and butter into the paste.
- Ratafia biscuits
- Add almond aroma and a finely crumbed flavour to the paste.
The step that matters
Drying the paste after adding the flour. Stirring the flour into the boiling liquid and then cooking it for 2 minutes gelatinises the starch and drives off moisture. A dry, cohesive paste holds its shape and puffs properly, while a wet one spreads and stays flat.
