Place butter and sugar in a large bowl; beat with a mixer at medium speed for 5 minutes or until light and fluffy. Add egg, 1 tablespoon lime rind, and lime juice; beat 2 minutes or until well combined.
Weigh or lightly spoon flour into dry measuring cups; level with a knife. Combine flour, baking powder, and 1/8 teaspoon table salt; stir with a whisk. Add flour mixture to butter mixture, and beat just until combined.
Divide dough into 2 equal portions. Shape each portion into a 6-inch log. Wrap logs individually in plastic wrap; chill 3 hours or until firm.
Preheat oven to 350°.
Cut each log into 16 (about 1/3-inch-thick) slices, and place 1 inch apart on baking sheets lined with parchment paper. Sprinkle the cookies evenly with remaining 2 teaspoons lime rind, turbinado sugar, and sea salt. Bake at 350° for 10 minutes or until edges are lightly browned. Cool for 2 minutes on pans on a wire rack. Remove from baking sheets, and cool completely on wire rack.
Place vanilla ice cream and sherbet in a medium bowl; lightly fold and swirl together. Scoop 1/4 cup ice cream mixture onto bottom of one cookie, and top with one cookie. Cover each sandwich with plastic wrap; freeze 4 hours or until firm.
These are DELICIOUS. Made them on two different occasions for dinner parties and guests who normally don't eat sweets totally devoured them. Yes, these are time consuming, but great when you want to highlight dessert in the summer.
These were a huge hit at a recent party. I made them "mini" ice cream sandwiches since it was for a large crowd. The cookie dough was way too tough especially the 1st batch. Beat the 2nd batch of sugar and butter for at least 20 minutes to get it light and fluffy.
I will make them again but I will modify the recipe for a soft cookie. Also the lime sorbet was not green so instead I lightly coloured coarse sugar to sprinkle on top before baking the cookies.
Great! I disagree with other reviewers who thought the cookie part was too tough, mine were just right. Great for a small dessert fix. I will definitely use this recipe as a base for other flavor combinations! Give it a try!!
This dessert sounded better than it turned out. The cookies were the best part and would be better eaten with a hot cup of tea. However, the frozen result was extremely hard to bite into and in the end, not as much flavor as expected. There are much better frozen dessert recipes out there that are much less time consuming and better tasting. I won't make this one again, but it was fun to try. I gave it two stars because I think the dessert has potential (like eliminating the vanilla ice cream as it took too much of the lime flavor away) but I don't like it enough to experiment.
These sandwiches were really tasty. The sugar cookies are deliciously sweet and salty on their own but the sherbert ice cream addition makes them even better. Tangy, sweet, salty- these have everything!
