Herbed Pastry

In the work bowl of a food processor, combine flour and salt. Add butter, and process for about 10 seconds, or until mixture resembles coarse meal. Add thyme and shallots; process a few seconds more.

With the machine running, add water little by little, until dough just holds together. Form dough into a flat disk, and wrap in plastic. Chill until firm, at least 30 minutes.
