In a bowl, combine the dry ingredients – flour, salt, and sugar.
245 gs all-purpose flour, 1/2 tsp salt, 20 gs granulated sugar
Place the cold butter* on top of the dry ingredients, then rub it into the flour mixture using your fingers until there are flat, irregular strips of butter in the dough. Don't overwork the mixture*. If the butter is getting too soft, let it chill in the fridge for 10-15 minutes before continuing.
170 gs unsalted butter, frozen and cut into squares
Combine the water (with ice cubes) and the apple cider vinegar. Start adding the cold liquid mixture* into the dough, a little at a time, and mix it in. Add the liquid gradually until the dough just holds its shape when pressed together. You will likely not need to use the entire liquid mix, make sure you are adding it a little at a time.
50 ml water, with extra ice
Transfer the dough to a baking sheet and press it together gently to form a rough rectangle, a few crumbs and uneven edges are okay. Cut the rectangle into three parts and stack them on top of each other and press down on them using your palms and create a new rectangle. Press any crumbly bits into the dough then repeat the process. This creates a faux lamination in the dough and results in flaky, crunchy layers.
100 ml apple cider vinegar
Divide the dough into two and wrap each part tightly in cling film. Let the dough chill in the fridge for at least one hour before rolling it. You can freeze the dough and use it for up to 3 months.
To roll out the pastry dough, place it in between two baking sheets, then roll it to 2-3mm thickness. Cut circles out of the sheet of dough using a circular cookie cutter or a jar lid (2 circles for each pie).
Assemble the pie: Add around 1 tablespoon of peanut butter on one circle for each pie, then top it with a tablespoon of jam. Place the other circle on top of the filling as closely aligned as possible with the bottom as possible dough ring. Seal the pie by pressing the edges of both circles together, then further seal them using the edge of a fork.
200 gs smooth peanut butter, 200 gs strawberry jam, storebought or homemade
Brush the pastry with the egg wash and sprinkle granulated white sugar on top. Bake the pie until the crust is golden brown. Serve while still hot. But be careful, the filling might be too hot!
