Shoulda got regular peaches instead.

I just bought the dern thing two days ago, and it's already turning. It was firm as a rock when I bought it. Had I known this, I would have ate it sooner.

'Sumerwhite peaches and nectarines ripen much quicker than yellow varieties. If placed in a paper bag, Summerwhite peaches and nectarines ripen twice as fast - in about a day. Therefore, they should be checked often for softness.'
