Rainbow CookiesEllen Silverman

After receiving three letters about rainbow cookies with practically identical recipes attached, we knew we had to try them.

Andrea Giordano of North Babylon, New York, loved rainbow cookies as a child and was thrilled to be able to get the recipe from a coworker.

Stephanie Lenzo, of Kings Park, New York, wrote, "These have to be my favorite Christmas cookies of all. They are part of my holiday tradition."

Tracy Tortora of Marion, Massachusetts, calls these cookies Venetians and said they were the best from the assortment her grandmother baked every Christmas.
