I walked into Whole Foods Grocery Store to return gift items at the Amazon Customer Service Center and walked out with Louisiana sweet potatoes. The sweet potatoes were right inside the entrance to the store. Too tempting to walk by them without purchasing several. This root vegetable has lots of nutritional value. Plus, they are in season and inexpensive. So, there you go — three good reasons for why to purchase sweet potatoes. Today, I am making “Duchess Sweet Potatoes” which is a jazzed up concoction of mashed potatoes. I added browned butter with sage to give a upscale flavor. I even located my pastry piping bag and star tip to bake the potatoes little swirl shapes which is what makes “Duchess Sweet Potatoes” special. These creamy potatoes are just as good for when baked in a casserole dish as piped onto a platter for a fancy holiday dinner.
