Key Lime Paletas

Makes about 8 3-ounce paletas:

6 oz (3/4 cup) Key lime juice – from approximately 20 Key limes or 6
regular limes
1 tablespoon Key lime zest
14 oz can (1 3/4 cup) sweetened condensed milk
8 oz (1 cup) plain Greek yogurt
Pinch of salt
2 or 3 cups crushed graham crackers

• Zest limes until you have about 1 tablespoon and add it to a
  medium-sized bowl. In a small measuring cup, juice enough limes until
  you have 3/4 cup of fresh lime juice. Add it to the bowl with the
  zest. Whisk in the sweetened condensed milk, Greek yogurt, and a pinch
  of salt. Whisk again to combine.
• Divide the mixture among the ice-pop molds filling almost to the top
  and insert a stick into each. Transfer to the freezer and freeze until
  solid, about 5 hours.
• While the paletas are freezing, prepare the crushed graham crackers by
  pulsing in the bowl of a food processor until they look like coarse
  sand. Set aside in an air-tight container until the paletas are ready.
• To serve, pour the crushed graham crackers onto a plate. Dip each
  ice-pop mold in warm water for about 10 seconds to unmold. Press each
  side into the crushed graham crackers making sure to coat completely.
