Baking 90 Count Potatoes For 250 People

Aug 12, 2015
Q: I read your article about cooking large quantities of baked potatoes and putting them in a cooler to keep them hot. We do a fish dinner every year during Lent and cook about 250 potatoes a week for 6 weeks.  Do you have any data on how long it takes for the baked potatoes to reach 185 degrees F? We wrap (I know, I know) the potatoes and put about 30-35 potatoes on a full size sheet pan. We put in two racks per oven. Normally we set the commercial gas oven to 500 degrees F. Is it better to cook them at 400 degrees F?

Storing Potatoes And Dealing With Black Spots

Aug 3, 2015
Q: We have a restaurant located in Mountain Home, Arkansas. We buy all of our restaurant needs from Performance Foodservice.  We are currently buying your potatoes (approximately 15 to 20 cases per week).  When our delivery comes (twice a week), our potatoes come in off the truck and appear to be in good condition, wet and cool from the humidity from a refrigerated truck.  The potatoes temp between 50-55 degrees.  It has been a very hot and humid summer here.  Today, for instance, our heat index are in the triple digits.  The potatoes appear to be solid and in good shape.  We bring them into the restaurant, we have a stored area under a window with a window air conditioner blowing right on them.  We immediately foil wrap about 3/4 of them and put them back under the window until the potatoes are used.  The air conditioner is set as low as it can go, but at times, it seems blows out warm-ish air.  We use the potatoes within a week.  When we take the potatoes over to start wrapping them, some of the potatoes have black spots on them (pictures attached).  Some that appear to be good are wrapped and stored but when cooked they turn to mush and stink.  We do cook them in foil.  We tried cooking them without foil but customers complained about them getting cold.  It does get very hot in the kitchen.  We have had to complain to our vendor on a weekly basis for the past 6-8 weeks.  Do you feel it is something on the vendor’s side or are we doing something wrong in our restaurant? Any information and advice would be greatly appreciated.
