Drizzle ice cold water over the mixture in 1 Tablespoon amounts and mix with a wooden spoon until it starts to form a dough. It usually takes about 2-3 Tbsp, but you may need to add up to 5 Tbsp (amounts as original recipe is written // adjust if altering batch size). It should be moist enough to form into a ball, but not too sticky to handle. Add more flour if it gets too wet.
Cut into 16 equal squares (amount as original recipe is written // adjust if altering batch size) and carefully transfer to a baking sheet. My first attempt, I got 12 squares. Then I rolled out my scraps and got four more!
Place about 1 Tbsp of the fruit filling onto half of the squares, leaving a 1/4 inch border to seal the edges. Then use your finger to run water around the edges so the two squares stick together. Top the squares with their matching halves and then seal lightly with a fork.
