1960s recipe from old Sprite advertising
1 6-oz. pkg. lime Jell-O
2 cups hot water
1/2 cup to 1 cup bottled lime juice (though I bet fresh lime juice would be better)
2 12-oz. cans frozen concentrate for limeade
90 oz. Sprite
1 tsp. almond extract (this is mentioned in the ingredients list but not the recipe; use your discretion)
Dissolve gelatin in hot water. Then stir in frozen limeade concentrate. Add lime juice.
To serve, pour into bowl over 1 1/2 quarts of cracked ice. Add Sprite.
If you like, add a fifth of vodka.
Makes about 48 4-oz. servings.
A little mod inspiration — Carnaby Street in London, all decked out for Christmas in the 1960s.
