Corn Skewers 4 "not on the b b q" Doreen 27 May 2013 Love these skewers, bought them last year while in England. Have used them over the Winter in the microwave or steamer and, yes, you can insert the skewer before cooking using these methods of cooking corn. Today while using the b b q I managed to melt my lovely skewers. So, my advice, don't preinsert them if cooking over hot coals, thus only 4 stars awarded. Looks like I had better order some more! A note from the team Thanks for placing your review. We're sorry that the skewers melted when placed on the BBQ, but as they are made from polypropylene, they won't stand excessive heat.The manufacturer does not recommend they be put in the microwave either.
