Twice-Baked Sweet Potatoes with Citrus and Mascarpone

Serves 10–12 / From Sarah Stegner, dining room chef, The Ritz-Carlton, Chicago. Stegner, a Chicago native, promotes a seasonally driven menu featuring top-quality produce from small, local farmers. She also helped develop Chicago’s Green City Market, the city’s only venue featuring regional, sustainable produce. For the harvest holiday, her natural pick is sweet potatoes. “Almost everybody has some form of sweet potato on Thanksgiving,” she says. “This is a way of dressing it up and making it something special.” The consistency of the purée should be very light, “not thick like mashed potatoes.” View recipe.
