The refreshing sweet-tart flavor of these crumbly cookies is just right after a spicy meal. Other citrus juices and zests can be substituted for the lime juice and zest.

Ingredients
Preparation
Step 1
Put butter and 1/3 cup confectioners’ sugar in the bowl of an electric mixer fitted with the whisk attachment, and mix on medium speed until pale and fluffy. Add the lime zest and juice and the vanilla, and mix until fluffy.
Step 2
Whisk together flour, cornstarch, and salt in a bowl. Add to butter mixture, and mix on low speed until just combined.
Step 3
Divide dough in half. Place each log on an 8 by 12-inch sheet of parchment. Roll in parchment to form a log 1 1/4 inches in diameter, pressing a ruler along edge of parchment at each turn to narrow log. Refrigerate logs until cold and firm, at least 1 hour.
Step 4
Preheat oven to 350°F. Remove parchment from logs; cut into 1/4-inch-thick rounds. Space rounds 1 inch apart on baking sheets lined with parchment paper. Bake cookies until barely golden, about 13 minutes, rotating sheets halfway through. Transfer cookies to wire racks to cool slightly, 8 to 10 minutes. While still warm, toss cookies with remaining 2/3 cup sugar in a resealable plastic bag. Cookies can be stored in airtight containers at room temperature up to 2 weeks.
