Rough Puff Pastry

Ingredients

Directions

Make the dough

  1. Sift the flour onto a clean surface.

  2. Cut 3 oz. of butter into the flour.

  3. Make a well in the center and add the egg yolk and lemon juice.

  4. Mix in enough cold water to form a soft dough.

Laminate and fold

  1. Roll out the dough thinly and place one-third of the remaining butter on top.

  2. Fold the dough in thirds and turn it so the open end faces you.

  3. Repeat this process three times, then roll out for use.

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

What each ingredient does

Flour
Forms the gluten network that gives the dough its structure.
Butter
Forms separate fat layers that create flakiness when the pastry bakes.
Egg yolk
Adds richness and helps bind the dough.

The step that matters

Keeping the butter cold while folding. If the butter softens and blends into the dough, it will not form distinct layers. Cold butter stays in separate sheets, and as it melts in the oven the steam it releases lifts the layers apart, producing flakiness.

Swap the lemon

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

  1. Raisinfits better
  2. Vanillafits better
  3. Lemonthe original
  4. Coconutfits about as well

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