Lime Squiggles

These cookies are a style of shortbread called meltaways; the addition of cornstarch to the buttery dough reduces gluten development and makes them melt-in-your-mouth tender. Claire Saffitz supplements the butter with cream cheese, which adds extra tang on top of the lime juice and zest, then coats the finished cookies in a lime glaze rather than the usual powdered sugar. Piping them spritz-style through a wide star tip creates more surface area for the glaze and gives the cookies an extra-fun look. Make sure to cool them completely before dipping them in the glaze so it doesn’t fully drip off.
