Instructions: In the bowl of an electric mixer fitted with the paddle attachment, mix the flour, butter, cream, vanilla, and salt until smooth. Flatten dough into two equal discs, and wrap in plastic. Chill until firm, 2 to 3 hours.

Arrange rack in middle of oven. Heat oven to 325 degrees. Line three baking sheets with Silpats (French nonstick baking mats).

On a well-sugared surface, roll out dough, one half at a time, to a 1/8-inch thickness, continuously sprinkling sugar over the dough while rolling. Using a 2-inch heart-shaped cutter, cut out 72 heart shapes. Place 24 cookies on each baking sheet. Chill all cookies until firm, about 10 minutes.

Bake cookies, one sheet at a time, until light golden brown, about 15 minutes. Transfer to a rack to cool.

In a small bowl, stir the jelly until smooth. Place jelly in a small pastry bag fitted with a #11 plain round tip and pipe 1/2 teaspoon per cookie on half of the cookies. Place remaining cookies on top to form sandwiches.

This recipe yields about 36 cookie sandwiches.
