I just made a lemon meringue pie. Do you add a little bit of cream of tarter to your meringue? Make sure your bowl is grease free and no yolks get in your whites. Add the sugar slowly and beat well after each addition. Beat the whites long enough but don't over beat. Put the meringue on hot filling and seal it to the edges.
I have made pavlova it is so good. Nice light desert.
