Whisk together flour and salt.
Cut in shortening until it is the size of small peas or smaller.
With a fork, stir in the water 1 tablespoon at a time until well mixed.
Using hands, gently squeeze the pastry together until it adheres in a ball.
Flatten the ball on a sheet of waxed paper or a pastry mat.
Cover it with a second sheet of waxed paper and roll it into a 12-inch circle.
Peel off the top paper.
Cut rounds of pastry with a 2-½-inch biscuit cutter.
Place pastry rounds on a baking sheet about ½-inch apart.
Reroll pastry scraps and cut rounds until all the pastry is used.
Lightly brush each round with water.
Cover each with Spiced Sugar or Cinnamon Sugar.
Prick each round once or twice with a fork.
Press a pecan half into the center of each round.
Bake at 400°F for 8 to 10 minutes or until pastry begins to brown.
