Frozen Margarita Pie

1. 1

   In a 3- to 4-quart pan over medium heat, stir marshmallows with half-and-half until melted, about 5 minutes.

2. 2

   Nest pan in ice water; stir often until cool, about 3 minutes. Add lime peel, lime juice, and tequila; stir occasionally until cold, 8 to 10 minutes.

3. 3

   In a food processor, whirl cookies until finely ground. Add butter and whirl until mixed. Press cookie mixture evenly over bottom and halfway up sides of a 9-inch cake pan with removable rim.

4. 4

   In a bowl with a mixer on high speed, whip cream with sugar until it holds soft peaks. Fold in marshmallow mixture, blending well.

5. 5

   Pour filling into crust and spread level. Freeze until firm to touch in the center, about 1 hour, then wrap airtight and freeze until solid, at least 2 hours longer or up to 2 weeks.

6. 6

   Unwrap pie, run a thin knife between crust and pan rim, and remove rim. Set dessert on a flat plate. Let stand at room temperature about 10 minutes to soften slightly, then cut into wedges.

7. 7

   Use a silver tequila.
