While Langues de Chat, or “Cats’ Tongues,” garner their name from their long, flat shape, their flavor is melt-on-your-tongue delicious. Our variation calls for finely ground pistachios and lemon zest, amping up the flavor but keeping the traditional – and delectable - crisp on the outside, soft on the inside texture. We'll ask again: cat got your tongue?
2/3 cup unsalted butter 2/3 cup granulated sugar 1/2 teaspoon lemon zest 2 egg whites 1 cup all-purpose flour 1 teaspoon kosher salt 2/3 cup ground pistachios 1 teaspoon pure vanilla extract
Whisk together flour, salt and ground pistachios. Set aside.
Cream butter and sugar together until the mixture becomes light and fluffy. Add in lemon zest and process to combine one minute longer. Add egg whites one at a time and mix to combine. Add flour, salt and ground pistachios until smooth.
Fit a piping bag (or plastic bag) with a number three tip and fill bag with dough. Chill 1 hour.
Pipe into 2-inch long strips and bake 7-10 minutes at 350 F, until the edges begin to brown. Cool completely on rack before serving.
