Mix the yolks, 1/4 c sugar, the remaining juice, salt, and grated zest in a sauce pan. Boil gently over a low flame, stirring constantly until it thickens enough to coat a spoon. It will be about 160 degrees F.
Remove the yolk mixture from the heat, and stir in the gelatin in the juice. Stir occasionally while whipping whites.

Fold whites into yolks. Pour filling into pie shell. Cool at least 4 hours in the refrigerator.
