Mush together purchased ice cream, lemon curd (found near the jellies and jams), and limoncello, and you get a delicious lemony version of a Creamsicle—fruit-tangy and creamy-milky at the same time. Meringue cookies add welcome crunch.
Combine curd and liqueur in a small bowl, stirring with a whisk to blend. Add ice cream to curd mixture; stir to blend. Spoon 1/2 cup ice cream mixture into each of 4 bowls; top each with 1 crushed meringue cookie.
