Instructions

  1. Place a medium sized bowl and a set of beaters in the refrigerator to chill.
  2. Bake pie crust according to directions and let cool; Refrigerate until ready to use.
  3. Combine the watermelon and granulated sugar in a very large bowl; using a potato masher, mash until the mixture is quite liquid; set aside for 15 minutes.
  4. After 15 minutes, drain the mixture through a strainer, reserving almost 2 ¾ cups of the watermelon juice and then discard pulp and seeds.
  5. Put ¼ cup of the juice in a medium size bowl and sprinkle the gelatin over it; set aside for 3 to 4 minutes to dissolve.
  6. Heat ½ cup of the juice in a small saucepan over medium heat (or in the microwave) to a near boil; whisk the hot juice into the dissolved gelatin.
  7. Pour the remaining 2 cups watermelon juice into a large bowl an stir in the gelatin-watermelon juice mixture; stir in the lime juice; place in refrigerator.
  8. Using an electric mixer, beat the egg whites in a medium size bowl until stiff peaks form; set aside; clean and dry beaters;
  9. Using the chilled medium-size bowl and chilled beaters, beat the heavy cream with the mixer until it holds soft peaks; add the confectioners’ sugar and beat until smooth and stiff but not grainy; refrigerate.
  10. When the watermelon juice mixture starts to firm up, add about one-quarter of the whipped cream and beat with the electric mixer until smooth.
  11. Add the beaten egg whites and remaining whipped cream and gently fold them in with a large rubber spatula; if necessary, use a whisk-very briefly- to smooth the mixture and break up any large globs of whites or whipped cream;
  12. Pour the filling into the cooled pie shell; shake to settle; cover with loosely tented aluminum foil and refrigerate for at least 4 hours, preferably overnight.
  13. To serve, garnish each slice with a dusting of confections’ sugar, and then add a dollop of whipped cream, if desired.
