Why it works: Flour and butter 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 ↓
French Puff Pastry
Ingredients
Directions
Sift the flour through a wire sieve.
Mix the yolks with lemon juice and enough cold water to form a soft paste.
Knead the mixture until smooth and roll it out into a long strip.
Wrap the butter in a floured towel and squeeze out moisture without softening it.
If it's hot, chill the butter in the ice for 30 minutes before use.
Shape the butter into a flat cake slightly smaller than the pastry.
Place the butter on one end of the pastry, wet the edge slightly, and fold the pastry over the butter.
Seal the edges well, turn it around, and press with a rolling pin.
Roll it out, fold it in thirds, and let it rest in a cool place for 15 minutes.
Repeat the rolling and folding process seven times, resting for 15 minutes between each.
Before the last two rollings, sprinkle a few drops of lemon juice over the pastry.
Always arrange the pastry with rough edges facing you and keep the edges as square as possible.
After the final rolling, cover the pastry with a damp cloth and refrigerate for at least 2 hours, or preferably overnight.
