Just a helpful hint to anyone who chooses to make this: Try chilling the beaters, bowl and milk before whipping and you will find that it whips more easily. The peaks will be "soft" peaks, unlike those of whipped cream or egg whites.
This was really good and easy to make, but I could not get it to whip into peaks. I must have whipped it for about 10 minutes. I added the jello, and poured into the graham pie shells. It tasted great, and I have been eating it like crazy. The only thing I don't think it was as fluffy as it probably should be, maybe I didn't chill the milk long enough. I love how it is such a light taste, but full of flavor. Good recipe, thank you.
