You do need to thaw the Cool Whip in the refrigerator (at least 5 hours) before using. Don't try to do it straight from freezer. It won't mix properly with the other ingredients. | The recipe uses 6oz of limeade, but I can only seem to find 12 oz containers, so I just measure out 6 oz with a measuring cup. DO NOT use the whole thing of limeade. Your pie will most likely come out too watery and won't set properly. | Be sure to refrigerate the pie AT LEAST 8 hours before cutting and serving. While this isn't a super-firm pie, you still want it properly set before you try to cut and serve. I also like to stick the pie in the freezer for about 10 minutes before serving. It makes it much easier to cut (especially those first slices!)
