For the Lemon Glaze, follow my instructions for combining the confectioners sugar, fresh lemon juice and vanilla extract.
Clean, dry and and trim pansy flowers, trimmed as close to the flower as possible. Then gently place them on the icing while wet, so they adhere.
In addition to pansies, violets and borage are would also look lovely on your cookies. Rose petals and lavender buds are other options as well.
