Step 1: Ingredients
1 tablespoon finely ground English breakfast tea leaves (from about 2 bags)
1/2 teaspoon coarse salt
1/2 cup (1 stick) unsalted butter, softened
1/4 cup confectioners’ sugar
2/3-ish tablespoons finely grated orange zest
Step 2: Instructions
Put butter, sugar, and orange zest in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until pale and fluffy, about 3 minutes. Reduce speed to low; gradually mix in flour mixture until just combined.
Divide dough in half. Transfer each half to a piece of parchment paper; shape into logs. Roll in parchment to 1 1/4 inches in diameter, pressing a ruler along edge of parchment at each turn to narrow the log and force out air. Transfer in parchment to paper towel tubes; freeze until firm, 1 hour.
Preheat oven to 350 degrees. Cut logs into 1/4-inch-thick slices. Space 1 inch apart on baking sheets lined with parchment.
Bake cookies, rotating sheets halfway through, until edges are golden, 13 to 15 minutes. Let cool on sheets on wire racks.
