Need some help - have 15 lb bag of red potatoes. Will be making roasted potatoes with rib eye roast the 1st night and want to make mashed potatoes for a roast chicken the second night. Can I successfully use red potatoes? Traditionally, I use Yukon Gold potatoes for mash, but I don't want to buy another bag. Do I need to make any substitutions like cook longer/shorter, use more/less dairy, etc?
If I can't make mashed potatoes, what else beside roasted potatoes do you suggest? Family will be disappointed, but.... Thanks!
