Step 1

Preheat oven to 325 degrees F. Line a baking sheet with parchment.

Step 2

Beat the butter until light and fluffy in a bowl. Sift together the salt, all-purpose flour, and cayenne in another bowl. Add flour mixture to butter mixture and mix just until incorporated. Add cheese and rosemary and combine just until incorporated.

Step 3

Break off pieces of dough and shape into 1 to 1 1/2-inch balls. Add to baking sheet lined with parchment paper. Press down balls to flatten. Chill in the refrigerator until firm, about 15 to 30 minutes.

Step 4

Bake in the centre of the oven until edges are lightly golden, about 25 to 30 minutes. Cool on baking sheet on a wire rack, about 10 minutes. Transfer to wire racks to cool completely. Store in an airtight container.
