Directions

Preheat oven to 350°F. Beat together butter and sugar until fluffy.
Beat in egg, lemon peel, lemon juice, and salt.
Stir in 2 cups of flour - use additional flour if needed to make a firm dough that holds together. Form into 1-inch balls. Place on lined or greased cookie sheets about an inch apart. Using finger or a deeply rounded measuring spoon, make a deep depression in each cookie.
Fill with one teaspoon of preserves or marmalade.
Bake until cookie is firm and lightly browned, about 20 minutes. Let cool on a rack before eating.
