1. Place flour, margarine, nutmeg and salt in a food processor and process 10 seconds to a cornmeal texture. With processor running, add 1-1/2 T. ice water. Add remaining water slowly, and stop the machine as soon as the dough begins to form a ball. Tiny pieces of margarine should be visible in dough.

2. Form the dough into a ball and flatten into a thick dish. Flour your work surface and rolling pin and roll dough from center out to sides, turning into a perfect circle about 10 inches in diameter.
