Citrus Slice Cookies

In large bowl, beat butter, sugar, vanilla and eggs with electric stand mixer on medium-low speed or with electric hand mixer on lowest speed until well combined. Add flour and salt; beat until soft, nonsticky dough forms. (You should be able to handle the dough without it sticking to your fingers. If dough is sticky, beat in additional flour 1 tablespoon at a time until the dough comes to the correct consistency.)

On work surface, shape dough into a ball. Divide into 3 equal portions. Return one-third of dough to bowl; beat in orange peel, orange extract and drops of yellow and red food color until orange color is consistent. Remove dough from bowl; cover with plastic wrap.

Clean bowl; add another one-third portion of dough. Beat in lemon peel, lemon extract and drops of yellow food color until yellow color is consistent. Remove dough from bowl; cover with plastic wrap.

Leave remaining one-third of dough plain; cover with plastic wrap.

Refrigerate all dough portions 1 hour.

Shape each portion of tinted dough into a roll about 5 inches long and 2 1/2 inches in diameter; set aside. On lightly floured work surface, roll plain dough into a rectangle. Place roll of orange dough on plain dough. Roll plain dough in a single layer around orange dough. Cut away excess dough; reserve for yellow dough.

Place orange sanding sugar on plate; roll dough log in sugar until completely coated. Wrap sugar-coated dough log in plastic wrap; refrigerate. Repeat process with lemon dough, remaining plain dough and yellow sanding sugar. Refrigerate dough logs at least 4 hours.

Heat oven to 400°F. Line cookie sheets with cooking parchment paper.

Cut chilled logs into 1/8- to 1/4-inch-thick rounds. With back edge of knife, score “segment” lines into each round, making only indentations (do not go all the way through). Cut rounds in half; place on cookie sheets.

Bake 6 to 8 minutes or until set. Remove cookies from cookie sheets to cooling racks. Cool completely.
