At first I thought this was a problem that had to do with cooking. After googling "Excel Potato pearls" I see that it has nothing to do with cooking. Perhaps they are best microwaved to order.
Also if a product has time to "break down" then, to me, that says it is being overprepped as well as being held too long.
Considering the rates I have see at standard operating temperatures (piping hot at 175~180 F) I venture a guess that one of America's most popular sidedishes is being held for more than 3 hours. Business alright?
lol: ~$70 dollars a case for mashed potatoes.
