Whenever I make jam I want want to make thumbprint cookies.
1/2 cup butter, softened
1/4 cup brown sugar, packed
1 egg (separated)
1/2 teaspoon vanilla extract
1 cup flour
1/4 cup finely chopped walnuts
2/3 cup jam
1/4 teaspoon salt
Preheat oven to 300 degrees F. Grease cookie sheets.
Separate egg, reserving egg white. Cream butter, 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.
