Puff Paste

Ingredients

Directions

  1. Place the flour on a clean surface and make a well in the center.

  2. Add the egg yolk and lemon juice into the well.

  3. Using your fingers, mix the flour, egg, and lemon juice into a firm paste, adding cold water as necessary.

  4. Remove any whey and buttermilk from the butter and shape it into a flat cake.

  5. Roll the paste into an oblong shape and place the butter in the center.

  6. Fold the edges of the paste over the butter to completely cover it.

  7. Gently flatten the covered paste with a rolling pin.

  8. Chill the paste in a cold place or on ice for about 10 minutes until firm.

  9. Roll the paste out evenly in one direction, keeping the edges straight.

  10. Fold one edge to the middle, then fold the other edge over it to meet perfectly.

  11. Ensure the edges are even and straight, then turn the paste and roll in the opposite direction.

  12. Repeat the folding process and chill again until cold.

  13. Roll out a total of six times for pastry or eight times for vol-au-vents.
