Ah, to make meringue. We never made any in school. I had some leftover egg whites from making custard-based ice cream, so I thought I could make meringue for a pie my sister was making.
The process, it turns out, is not that complicated. There are 3 types, according to my textbook. The “common” meringue does not require any heat, but only that you whip the whites to soft peaks before adding the sugar. I tried that. Didn’t work with the whites I had. So, I tried warming the same over a pan of boiling water, removing and whipping some more (Swiss meringue). By heating the whites, a Swiss meringue is more stable. Still no go. Maybe I should have started from scratch.
So, I disposed of those and made an Italian meringue. This is more stable than a Swiss meringue. It involves cooking sugar syrup to 240F, while whipping egg whites to soft peaks, then whipping in the syrup until the right consistency is reached. This worked. I also used a little cream of tartar to help the egg whites coagulate. Might have made a difference.
Bake at 400F until a nice golden brown is attained.
The process of making an Italian meringue is the same as beginning the process of making a buttercream. (For French buttercream, you use yolks instead of whites.)
Now that I know the technique, at some time I’ll try some alternative sweeteners, and post results.
