When she was asked about the secret to making delicious cookies, Susan Callahan, owner of Goodies Homemade’s answer was short and to the point: butter. I would second that.

This is Joanne Chang’s recipe for shortbread cookies and can be found on page 146 in her first Flour Bakery cookbook (Flour: Spectacular Recipes from Boston’s Flour Bakery + Cafe). Deliciously crisp with a hint of rosemary, this bake filled the air with the best and most buttery aroma ever.

The cookies can be shaped lots of different ways, but I’ve opted for squares and triangles. A great, not-so-fussy cookie that is easy to assemble and bake.

Have on hand:

• butter
• sugar
• vanilla
• egg yolk
• rosemary (fresh)
• unbleached AP flour
• cornstarch
• baking powder
• salt
