I over bought baby Yukon Gold potatoes. Could not resist them at the Farmer's Market, just dug up, clean and so tender. Plus, I already had some Dutch Gold I saw at Trader Joe;s. I had read a blogger's report on how she left the skin on baby potatoes, which she mashed, and how much her family loved them. So I did the same yesterday. I steamed my potatoes until tender, then added lots of good, organic, unsalted creamery butter, buttermilk and sour cream. Then a good dose of Himalayan sea salt and freshly ground black pepper, I used only a potato masher to do the mashing. This took no time at all. Oh my, this is a delightful method, so yummy and the skin adds extra flavor.
