Ingredients:1 cup butter, softened
3/4 cup packed brown sugar
2 egg
1 teaspoon vanilla extract
2 cups all-purpose flour
2/3 cup and 1 tablespoon finely chopped walnuts (optional)
1-1/3 cups any flavor fruit jam
1/2 teaspoon salt
Directions:Preheat oven to 300 degrees F. Grease cookie sheets.
Separate egg, reserving egg white. Cream butter or margarine, sugar, and egg yolk.
Add vanilla, flour and salt, mixing well.
Shape dough into balls. Roll in egg white, then walnuts. Place on cookie sheets about 2 inches apart. Bake for 5 minutes.
Remove cookies from oven. With thumb, dent each cookie. Put jelly or preserves in each thumbprint. Bake for another 8 minutes.
Since I'm allergic to nuts I opted to roll in white sugar, which turned out great. And made a very pretty cookie. I also found I needed to cook the cookies about 3-4 minutes longer during round two.
