1 cup flour
½ tsp salt
125g butter, chilled, finely chopped
¼ cup sour cream
Ingredients provided by:
Place flour, salt and butter in a food processor or large bowl and whizz, or rub between your fingertips, until mixture resembles crumbs. Add sour cream and continue to blend until the dough starts to incorporate into a ball. Check consistency – if it is still crumbly and does not come together, add a little cold water or more sour cream.
Tip dough onto a sheet of baking paper, pressing it together into a disk or log shape. Wrap and chill for at least 20 minutes before use. If not using within a week, freeze until needed.
