This recipe started out as a result of an overabundance of Yukon gold potatoes in my kitchen.  With just the Southern husband and me in the house, I like to buy things by twos, but at some point our local market didn't have loose Yukons.  Nope, they only had them in the 5 pound bag, and I needed my Yukons, so I went for the five pound bag. I finished making what I was making, and then I still had pounds of Yukons left over.  And since we have a strict no ingredient left behind rule around these parts, I needed to get inventive...and so I bring you cheesy hash brown nests, which used up a pound of those Yukons and led to ALL kinds of Southern husband happiness.  Got a pound of potatoes and a muffin tin?  Let's make them!
