Whisk the wet ingredients

• In a mixing bowl, whisk together the cold water, egg, vinegar and salt with a fork until well combined.

Cut in the shortening and flour

• Add the shortening first, then the flour.
• Mix well with a fork or pastry cutter until the mixture comes together.

Finish the dough by hand

• Finish working the dough with your hands until it forms a good ball.
• Add more flour only as needed, a little at a time.
• Do not over-mix the dough.

Use or store

• Use the dough right away, or place it in a ziplock bag and store it in the fridge.
