Key Lime Pie

• 1 ready-made graham cracker crust
• 1 can sweetened condensed milk
• 4 eggs
• 1/2 cup lime juice
• 1/2 teaspoon cream of tartar
• 1/2 teaspoon cornstarch

Preheat oven to 350 degrees. Separate eggs, save 3 whites for meringue. Beat egg yolks into sweetened condensed milk, add lime juice and mix thoroughly. Beat one egg white until stiff, fold into milk mixture. Pour into pie crust. Beat remaining egg whites with cream of tartar until foamy; add corn starch. Gradually add sugar to egg whites while beating, until stiff peaks form. Top pie with meringue; bake for 15 minutes or until meringue is golden brown.
