Several hours before serving, spoon softened ice creaminto a large mixing bowl and stir in lemon curd until
well combined. Return ice cream to carton or place in a
freezer-safe container and return to freezer.
Combine sugar and lemon zest in the bowl of a food
processor and process until zest and sugar are well
mixed and slightly damp. Pour lemon-sugar into a
shallow bowl.
Line a large platter with parchment paper and place
platter in freezer.
Remove ice cream from freezer and soften slightly before
assembling cookie sandwiches. Scoop a spoonful of
ice cream on top of one cookie. Place a second cookie
on top of ice cream and press down so that ice cream
reaches the edge of both cookies.
Roll edges of ice cream in lemon-sugar and place cookie
on platter in the freezer so it doesn't start to melt.
Repeat until you've used all the ice cream or have made
the number of cookies desired. Serve immediately or
store in freezer until ready to serve.
