Rough Puff Pastry

Ingredients

Directions

Prepare the dough

  1. Sift the flour and salt onto a pastry board.

  2. Cut the butter into large pieces, about 1 inch square, and coat in the flour.

  3. Make a well in the center of the flour, add the lemon juice and 1 tablespoon of water, and mix into a smooth paste, adding more water gradually.

  4. Knead the mixture thoroughly, then roll it out and fold in the butter.

Laminate and finish

  1. Roll out into a thin strip on a floured board with a floured rolling pin.

  2. Fold the pastry in thirds, press the edges together, and turn the fold to the left.

  3. Repeat the rolling and folding process until the pastry has had four rolls and four folds.

  4. Roll to the desired thickness and it's ready to use.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Flour
Forms the gluten structure that holds the layers of the pastry together.
Butter or lard
Forms separate layers that create flakiness as the fat stays solid between sheets of dough.
Lemon juice
Adds acidity that tenderizes the gluten, making the dough easier to roll.

The step that matters

Keep the butter cold and in large pieces while folding. If the butter softens or melts into the dough, it blends in rather than forming distinct layers, so the pastry loses its flakiness. Cold fat stays solid through each roll, and the steam it releases during baking lifts the layers apart.

Swap the lemon

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

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