Flourless Peanut Butter and Jelly Cookies

1 cup chunky or smooth peanut butter

1 cup sugar

1 egg

1 teaspoon baking soda

About 1/4 cup any fruit preserves-any you fancy

Preheat oven to 350 degrees F. In a mixer combine peanut butter and sugars until well combined, about 2 minutes.  Add egg and baking soda and mix for another 2 minutes.  The dough will be crumbly.  Roll into teaspoon sized balls and make a small indentation in the center of the dough ball with your pointer finger. Fill the depression with fruit preserves. Bake for 12 minutes, until lightly browned. Cool on a baking sheet for two minutes, then transfer to a wire rack to cool.
