Preheat oven to 400. Peel rutabagas and slice into fries a quarter to a half and inch thick. Soak in water for 30 minutes, drain and towel dry Toss in vegetable or peanut oil to coat lightly along with a few pinches of salt. Spread them out on a sheet pan without the fries touching. Bake until golden and tender, turning occasionally. Toss them with a bit more salt and fresh pepper and enjoy.
