Joseph Walker used only the finest ingredients to create his famous pure butter shortbread recipe, crafted in 1898 at his bakery in Aberlour, Scotland. More than a century later, Walker's remains one of the bestselling shortbreads in the world, still made with the same four high-quality ingredients: flour, butter, sugar, and salt.

But just knowing these ingredients doesn’t mean you know how to make great shortbread—a fact that’s best confirmed by giving any other copycat recipe a try. If a recipe calls for all-purpose flour and/or standard granulated sugar and salt, you’re destined for disappointment.  

The secret ingredient for perfect Walker's Shortbread cookies is pastry flour. It contains less gluten than all-purpose flour, resulting in a tender bite that mirrors the original cookies while providing a stable structure that won’t spread during baking. My favorite pastry flour is Bob’s Red Mill.

These cookies contain no leavening (hence their name, shortbread), so the sugar and salt are whipped into the butter until fluffy, creating air bubbles that help the shortbread rise moderately when baked. I'm using superfine sugar (baker’s sugar) and superfine salt (popcorn salt) to make shortbread with a clean bite, free of any detectable sugar or salt granules.
