We are having a dilemma here at work. The chef is making shoestrings today for a 400 count party, and for some reason, they are not crisping. She soaked them in cold water before frying, and never before have they not gotten crispy. It is raining today, but I don't think that's the reason. Could it be the starch content of the potatoes?They are Idahos. We tried russets this morning. Same. Please reply ASAP! Thanks.
