2 teaspoons finely grated lime zest (from about 1 large or 2 medium limes)
Pinch of salt
3 cups coarsely crushed graham crackers or Maria cookies
Directions
In a large bowl, whisk together the sweetened condensed milk, half-and-half, lime juice, lime zest and salt until well combined.
If you're using a conventional ice-pop mold, divide the mixture among the compartments, snap on the lid and freeze until solid, about 5 hours. If you're using drinking glasses or other unconventional molds, divide the mixture evenly among the molds, freeze until the pops are beginning to set (1½ to 2 hours), then insert sticks in them and freeze until solid, about 4 to 5 hours. If you're using an instant ice-pop maker, follow the manufacturer's instructions.
Spread the graham-cracker pieces on a large plate, unmold the paletas and press each side into the graham crackers to coat completely. Serve immediately.
