OK, I just can't seem to get this one right. I consistently find myself unable to properly remove the "string" from fresh snow peas. I usually get a tiny bit pulled off before the string breaks off--and thenI can't get at the rest of it without mauling the pod beyond recogntion. I've tried bending the end of the pod back first--and I've tried not doing that. I've also tried going extra slow, or fast-like removing a band aid. Nothing seems to make much difference in the result. Is there an actual technique for getting the whole string off every time?
