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 ↓

French Pastry

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.

Make the paste

  1. Boil the butter and cold water in a saucepan.

  2. Stir in the flour and sugar.

  3. Cook until the mixture pulls away from the sides of the pan, then remove from heat.

  4. Beat in each egg separately.

Shape and bake

  1. Dip a knife and two dessert spoons in hot water.

  2. Shape the mixture into egg-like forms.

  3. Place them on a greased baking sheet, spaced apart.

  4. Bake for 1 hour in a moderate oven (350°F / 175°C).

Fill and serve

  1. Once done, open the sides and fill with preserves or whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Gives the paste body so it holds its shape while baking.
Eggs
Set the structure and help the paste puff as steam forms.
Butter
Adds fat for a tender, rich texture.
Cold water
Turns to steam in the oven, helping the pastry rise and puff.
Castor sugar
Adds sweetness and helps the surface brown.

The step that matters

Beating in the eggs. Add each egg separately and beat until fully absorbed before adding the next. The paste must take up each egg completely, or it turns loose, which stops it holding its shape and puffing properly.
