Put the lemon curd in a bowl and mix with the limoncello.Whip the cream until stiff peaks form.Add half of the lemon curd to the whipped cream and gently fold with a rubber spatula, then add the remaining half.You should not get a uniform mixture: the desired effect is a whipped cream intertwined with lemon.Crumble the meringue by hand into the preparation and gently mix.Distribute into 4 glasses using a spoon and decorate with a few lemon zests.
