Step 1
For the Crust - whisk the flour and salt together in a large bowl. Add the chilled cubes of butter, and use your fingertips to break the butter in the flour until the largest pieces of butter are the size of peas. In a small bowl, whisk together the yogurt, lemon juice and ice water, then pour the mixture into the bowl with the flour. Stir gently to combine, adding a few teaspoons of flour if the dough is sticky, then gather into a ball, wrap in plastic, and refrigerate for at least 1 hour, or up to overnight.
