Start by placing the diced turnips in a large pot and fill it with water or bone broth until the turnips are covered. Bring the mixture to a boil, then reduce to a simmer and allow to simmer for at least 30 minutes. The longer you simmer, the less bitter the turnips will be.
While the turnips are doing their thing, cook the bacon (skillet or oven method both work). Make sure to keep 2 Tbsp of the bacon grease, then get rid of the rest. When the bacon is done, crumble it and set aside.
When the turnips are done, drain well. Then add all the remaining ingredients except for the bacon and chives. Give them a good mash until you have your preferred consistency before folding in the bacon and topping with fresh chives. Serve and enjoy!
