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 paste
Melt the butter with the milk, sugar, and lemon peel over medium heat in a stewpan.
Once it boils, remove from heat.
Quickly mix in the flour until it forms a paste.
Stir the paste over low heat for 2 minutes.
Add the eggs one at a time, mixing well after each addition.
Stir in the salt and ratafia biscuits.
Beat for 2 minutes.
Bake and fill
Drop spoonfuls of the mixture onto a baking sheet.
Bake in a gentle oven at 300°F (150°C) until golden.
Cut each petit choux open.
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
- Eggs
- Provide structure and lift, setting the choux as they cook and puff.
- Flour
- Forms the paste with the butter and milk, giving the pastry its structure.
- Butter
- Adds fat for tenderness and richness in the paste.
- Milk
- Provides moisture that turns to steam, helping the pastry puff.
- Ratafia biscuits
- Add almond aroma and a sweet, crisp flavour to the paste.
The step that matters
Quickly mix in the flour until it forms a paste. The paste must be fully cooked and smooth before the eggs go in. Stirring it over low heat dries the starch so the eggs incorporate well and the choux can rise instead of turning heavy or greasy.
