Why it works: Butter and flour 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 ↓

Puff-paste, Household

Oven, in the book's wordsA quick oven

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 paste

  1. Beat the water from the butter.

  2. Rub 2 ounces of butter into the flour until fine, then add a pinch of salt.

  3. Whisk the egg white.

  4. Mix in the lemon juice and a small amount of water.

  5. Stir this mixture into the flour to form a paste.

Laminate the dough

  1. Roll out the paste.

  2. Roll out the remaining butter.

  3. Lay it on the paste.

  4. Sift a little flour over it.

  5. Fold the paste into thirds.

  6. Roll it out twice.

Rest and bake

  1. Let it rest in a cool place for at least 1 hour, preferably 12 hours.

  2. Before using, roll it out very thin.

  3. Handle the paste lightly.

  4. Work in a cool environment.

  5. Bake in a quick oven at 400°F (200°C).

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

What each ingredient does

Butter
Forms separate fat layers that melt in the oven, creating flaky, puffed layers.
Flour
Provides the structure and gluten network that holds the layers together.
Egg white
Adds protein that helps the paste hold its shape and set when baked.
Lemon juice
Adds a little acidity that softens gluten, making the paste easier to roll.

The step that matters

Keep the paste cool while rolling and resting. Butter must stay firm so it forms distinct layers. If it softens and melts into the dough, the layers blend and the paste will not puff well in the oven.

Swap the lemon

How well each one fits the dish's main ingredients (butter, flour, egg):

  4. Coconutfits about as well

Fit is the average pairing score against butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
