In the work bowl of a food processor, place flour, loose tea, and salt; pulse until combined. Add cold butter, and pulse until mixture is crumbly. With processor running, add ⅓ cup (80 grams) ice water in a slow, steady stream until dough comes together. Wrap in plastic wrap, and refrigerate for at least 30 minutes.
