Puff Paste

Ingredients

Directions

Make the dough

  1. Rub ½ pound of butter into 1 pound of flour using your hands.

  2. Add enough water to form a paste with the consistency of the butter.

  3. Roll out the paste thin.

Laminate and fold

  1. Break ½ pound of butter into pieces the size of a shilling and distribute them over the paste.

  2. Fold the paste, let it rest for a short time, then roll it out again.

  3. Fold it up three times; it is now ready for use.

    Shared aroma: isobutyraldehyde (malty, green).

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

What each ingredient does

Butter
Forms the separate fat layers that create flakiness when the dough is folded and baked.
Flour
Provides the structure that holds the dough together and traps the layers between folds.
Water
Combines with the flour to form a workable paste that can be rolled and folded.

The step that matters

Distributing the butter pieces over the paste. Butter must stay in distinct pieces between dough layers. If it softens and blends in, the folds lose their separation and the pastry will not puff as well.
