History

The palmier arrived in Shanghai in the early 20th century through the Red House pastry shops, and Kaisiling and the Park Hotel later adopted and adapted the recipe for local tastes, reducing the sweetness to let the butter come through. The technique relies on repeatedly folding butter into dough to build up many thin layers, which puff and caramelise into a crisp, flaky wing shape when baked with sugar. The pastry stayed a fixture of Shanghai's Haipai bakery culture and drew fresh attention after the television series Blossoms Shanghai revived interest in the city's old institutions.

Make it at home

Yield Makes about 20Hands-on 45 minTotal 2 hr 30 minDifficulty Advanced

Ingredients

  • 250g plain flour
  • 1/2 tsp salt
  • 120ml cold water
  • 250g cold unsalted butter, in a block
  • 150g caster sugar, for laminating and coating

Method

  1. Mix the flour, salt and water into a smooth dough. Wrap and rest in the fridge for 30 minutes.
  2. Roll the cold butter between two sheets of baking paper into a rectangle a little smaller than the rolled out dough.
  3. Roll the dough into a larger rectangle, lay the butter on top, and fold the dough over to fully enclose it.
  4. Roll the dough out and fold it into three, like a letter. Chill for 20 minutes, then repeat the roll and fold three more times, chilling between each.
  5. Roll the laminated dough into a long rectangle, then sprinkle the surface heavily with sugar.
  6. Roll both short ends inward towards the centre until they meet, forming a double scroll, then chill for 20 minutes.
  7. Slice the scroll into 1cm rounds and lay them cut side up on a baking tray, spaced well apart.
  8. Bake at 200C for 15 to 18 minutes, turning once, until deep golden and the sugar has caramelised on both faces.

Tip from the editors. Keep the butter cold at every stage; if it softens and leaks out while rolling, the layers collapse into one dense sheet instead of crisp wings.
