For the forth day of the Gluten Free Dairy Free Holiday Cookie Countdown we have Lemon Shortbread.
To make lemon shortbread, simply add 1 tablespoon of very finely grated fresh lemon zest to the recipe for Gluten Free Dairy Free Shortbread. Easy-peasy! I will be making a triple batch, and packaging half for Christmas and half for Christmas gifts. Freeze in a sturdy freezer container with wax paper or baking parchment between the layers.
