All you need to balance out the bitterness of turnip is a touch of maple syrup.
Peel turnip and chop it into 1-inch cubes.
Heat a pan or wok on medium. Add duck fat, fenugreek and cracked pepper. Sauté 15-30 seconds, until the fenugreek begins to color.
Add onion and ginger. Cook for a few minutes, until onions are golden. Add turnip and cook for a few minutes until it is warmed through. Mash into a purée in the wok with a wooden pestle or potato masher. Cook 2-3 minutes more, stirring regularly. Salt and incorporate maple syrup.
