Sagamore Hill Sand Tarts

Cream butter and 2 cups sugar until light and fluffy. One at a time, add 2 eggs, beating after each is added. Beat in vanilla.

Separate remaining egg and add yolk to the mixture. Mix in flour and salt.

On a lightly floured board, roll out dough until thin. Using a shot glass (see note), cut out circles of dough, dipping rim of the glass in flour, as needed, to keep the dough from sticking.

Place dough on a greased baking sheet. Beat the remaining egg white slightly and brush on cookies. Mix the cinnamon and 1 teaspoon of sugar; sprinkle on the top of the cookies.

Bake in preheated 350 degrees F oven for 7 to 10 minutes, or until edges are light brown.

NOTE: A shot glass has a little less than a 2-inch diameter; the rim of a small jar also works.

These cookies were a favorite of the Theodore Roosevelt family. The recipe was written inside the cover of one of first lady Edith Roosevelt's cookbooks at Sagamore Hill, the family home on Long Island.
