Look to the rainbow and follow the fellow who follows the recipe. Impish, pastel colored sugar cookies are another sort of gold at the end of the rainbow. Roll up a stack of different colored doughs into a log. Then slice in round cookies, and then half again to form rainbow shapes and bake. These are bakery style, dense, buttery and crisp cookies that capture your eye and your heart in a single glance. Bake an extra batch for Finnegan. I used pink, yellow, lilac and green tints but you can use whatever hues you like (just green dough and white dough is perfect). Shortening gives this that bakery taste but all butter is always better. For some reason, these awesome cookies remain a most hit-on recipe at BB and it is a March/St. Pat's tradition to offer them free.
