Q: I am looking for some information and advice on our red B size 1 grade raw potatoes we boil. We parboil the potatoes in pots of water for approximately 25-30 minutes depending on size. We test using a fork to see how the potato falls off the fork. We then place on cookie sheets (use cold water to spray over when placed on sheets) and put in our walk in cooler (38 degrees) overnight to slice and spin in a machine the next morning.
We have noticed after we slice the potatoes the next morning that the cooked potatoes have a brown colored edge-ring around the skin and potato meat. The potatoes are then cooked on a flat top grill and we produce home fries. We obtain potatoes from all sorts of geographic regions according to the labels on the bags. Our vendor tells us they have to purchase potatoes from wholesale vendors and it is not possible to find a one stop supplier.
We have been told the sugar levels in potatoes varies, the potatoes are held in storage for months which creates the brown color rings and the potatoes are all sourced from different geographic locations and these different growing regions and processes leads to the brown colored rings. We always prepare our potatoes the same way and have noticed the winter months seem to be when the brown colored rings appear on the potatoes.
