to make custard
In a medium saucepan, combine the egg, remaining 1/2 cupsugar and cornstarch. Beat with a whisk or electric beater set on low speed until the sugar has dissolved and the mixture is smooth. (The mixture will appear dry at first, but will become liquid as you beat it.) Place the evaporated skim milk in a microwave safe measuring cup and heat 2 minutes on high until hot to the touch (this will reduce cooking time). Whisk the milk into the egg mixture while the pan is set over low heat. Cook, whisking constantly, until the mixture comes to a boil and thickens. If the mixture looks curdled, keep beating with a whisk until the lumps are incorporated into the pudding. Immediately remove from heat and stir in butter and vanilla. Allow to cool completely .Add one cup of vanilla nonfat yogurt. Can be made 3 days in advance and stored in the refrigerator.
Fill mini dessert glasses three quarters full of custard. Top with cranberry syrup. Finish with a dollop of whipped cream.
