Preheat oven to 275.
To start making the meringues, whip the egg whites until they start to get a little frothy. Add sugar about 1/4 cup at a time and add the cream of tartar with the first addition of sugar.
I read a lot of different suggestions for cooking time. I read 225, 275, 300 ... I decided to go with 275 and cook for an hour. Use the lower levels of the oven. You might need to adjust time or temperature based on your own oven.
