- 1 tablespoon heavy cream
- 3 tablespoons seedless raspberry jam
- 2 cups confectioners' sugar, sifted
- 1 1/4 cups all-purpose flour
- 1/8 teaspoon salt
- 10 1/2 tablespoons unsalted butter, melted
- 6 large egg whites, lightly beaten
- 3 drops Tulip Red gel paste food coloring
In a small bowl, mix together cream and jam until well combined; set aside.
In a large bowl, whisk together confectioners' sugar, flour, and salt; make a well in the center. Add butter, egg whites, and reserved cream mixture. Stir until well combined. Add food coloring, one drop at a time, stirring after each addition to combine. Refrigerate, covered, at least 2 hours or up to overnight.
Preheat oven to 375 degrees. Line two baking sheets with nonstick baking mats (such as Silpats).
When cookies come out of the oven, use a long offset spatula to quickly transfer cookies, one at a time, to a work surface; gently form into desired shapes; transfer to a wire rack, and let cool completely. Repeat process with remaining three cookies. If they harden too quickly, return baking sheet to oven for 30 seconds. Repeat with remaining batter. Cookies can be stored between layers of waxed paper in an airtight container at room temperature up to 3 days.
