1 tablespoon butter or margarine, softened
40 ounces cream cheese, softened
1 2/3 cups granulated sugar
5 eggs
1/8 teaspoon salt

Combine the first 3 ingredients; stir well, then set aside. Grease the bottom and sides of a 10-inch springform pan with butter. Add crumb mixture; tilt pan to coat sides and bottom. Chill.

Beat cream cheese at medium speed with an electric mixer until light and fluffy; gradually add the 1 2/3 cups sugar, beating well at high speed. Add sugar, beating well at high speed. Add eggs, one at a time, beating well after each addition. Stir in salt, vanilla extract and lemon juice. Pour mixture into the prepared crust. Bake at 300 degrees F for 1 hours and 20 minutes. The center may be soft, but will set when chilled. Cool on a wire rack; cover and chill for 8 hours.
