Hi, I wouldn't give up on it straight away, it may well be one that serves better as a winter squash, once cured and kept ,minimum 2-3 weeks but more is better, the starch will turn to sugar and it may well be better, don't know of course but if you get chance to get another one it might be worth a shot.I always thought the mixed commens on Bon Bon were because they could have been tasted too soon.
I will trial l it next year as I have no personal experience with this one and am curious.
