Step 1

In a large mixing bowl beat butter with an electric mixer on medium to high speed for 30 seconds.

Add the 1/3 cup powdered sugar, the lime peel, lime juice, the water, and vanilla.

Beat until combined, scraping sides of bowl occasionally.

Beat in the flour, cornstarch, and salt until combined.

Divide dough in half.

Shape each half into a 10-inch-long roll; wrap in plastic wrap.

Chill for at least 3 hours or up to 2 days.

Using a sharp, thin-bladed knife, cut rolls crosswise into 1/4-inch-thick slices.

Cool on cookie sheets for 4 minutes.

Place the 2 cups powdered sugar in a large bowl.

Gently toss warm cookies, two to three at a time, in powdered sugar.

Transfer to a wire rack and let cool.
