Preheat oven to 375 degrees F. For crust, in a bowl combine crushed graham crackers, walnuts, the 1 tablespoon sugar, and, if desired, the cinnamon. Stir in melted butter. Press the crumb mixture onto the bottom and about 2 inches up the sides of an 8- or 9-inch springform pan; set aside.

For filling, in a large mixing bowl beat cream cheese, the 1 cup sugar, the flour, and vanilla with an electric mixer until combined. Beat in milk until smooth. Stir in eggs and, if desired, lemon peel.

Pour filling into crust-lined pan. Place the pan in a shallow baking pan. Bake for 40 to 45 minutes for the 8-inch pan, 35 to 40 minutes for the 9-inch pan, or until a 2-1/2-inch area around the outside edge appears set when gently shaken.

Cool in pan on a wire rack for 15 minutes. Using a small sharp knife, loosen the crust from sides of pan; cool for 30 minutes. Remove the sides of the pan; cool cheesecake completely on rack. Cover and chill at least 4 hours before serving. If desired, serve with Raspberry Sauce.

Makes 12 slices

Water Bath Method: Prepare crust as directed. Place the crust-lined springform pan on a double layer of 18x12-inch heavy-duty aluminum foil. Bring edges of foil up and mold around sides of pan to form a watertight seal. Prepare filling as directed and pour into prepared pan. Place in a roasting pan and pour enough hot water around pan to reach halfway up the sides. Bake as directed. When done, edges of cake will be set but center will jiggle a bit when pan is gently shaken. Turn oven off and allow cheesecake to sit in oven for 1 hour (cheesecake will continue to set up during standing time in oven). Remove from water bath and cool and chill as directed in step 4.

Sour Cream Cheesecake: Prepare as above, except reduce cream cheese to 2 packages. Omit the milk and add two 8-ounce cartons dairy sour cream.
