I remember these as a Christmas treat my grandmother would make, and every year when my wife asks what kind of cookies I want, I say Lemon Squares. She usually says... you're supposed to make those in February and they are called 'Lemon Love Notes'. Its a good thing I'm flexible and happy to eat them in February too. The recipe for these can be found in The Smitten Kitchen Cookbook by Deb Perelman . Her recipes are reliable and she takes better pictures. Check out her book for the details.
