Blackberry Jam

  • In a medium saucepan, combine blackberries, sugar, and lemon juice.

  • Remove from heat.

Rough Puff

  • Combine flour, salt, and diastatic malt powder in the bowl of a stand mixer fitted with the paddle attachment.

  • Mix on low only to combine.

Notes

Substitutions:
  • Fresh or frozen blackberries can be used for the jam.
  • You can fill these turnovers with any flavored jam! A favorite of ours is Strawberry Jam or Raspberry Jam.
  • You can also used store-bought jam rather than make your own.
  • Store-bought puff pastry can be used, but we can't guarantee baking times.
 
Expert Tips:
  • While cooking the jam, mash the berries with your wooden spoon!
  • You can strain the seeds out if you want, but you will end up with much less jam and will not have enough to fill the turnovers.
  • When mixing the butter into the dry ingredients for the rough puff, be sure to leave some small-ish chunks of butter!
  • Do not add too much water to the dough!
  • Be careful to not over-mix.
  • Use the photos in the post above to help see the proper way to fold the pastry!
  • Don't skip refrigerating. This is SUPER important.
  • When shaping the turnovers, form the jam into a small triangle to help prevent spillage.
  • Be sure to brush the edges and the outside of the turnovers with the egg wash!
  • Every oven bakes differently. Keep an eye on the turnovers!
