Mix liqueur and sherry and brush both sides of each of the bread strips. Arrange liqueur-soaked bread strips around the sides of 8 stemmed goblets or individual glass bowls.
Whisk lemon curd to loosen, then whisk in zest. Beat heavy cream to soft peaks. Measure 1 1/2 cups of the whipped cream and stir into lemon curd.
Drop 5 to 6 raspberries into each of the 8 goblets or bowls. Spoon about 2 tablespoons of the lemon mixture over each portion of berries, then 2 tablespoons of the whipped cream over each portion of lemon mixture. Repeat once more with berries, lemon mixture, and whipped cream. Top with remaining raspberries. Cover with plastic and refrigerate until ready to serve. Can be made up to 8 hours in advance.
