Chef Marisa Iocco is putting the finishing touches on Blood Orange Extravaganza menus that’ll be available at both Bricco and Mare through the end of February. The three-course prix fixe menu at Bricco, based entirely on the sweet, vitamin-C-laden citrus fruit, costs $50 per person and includes courses like fennel souffle with blood orange coulis and blood orange-arugula salad; poached genovese of scallops and blood oranges with gnocchetti verdi; and blood orange sorbet paired with a chocolate “martini.” The Mare menu is four courses and costs $60 per person with dishes like peekytoe crab salad with blood orange mayo, monkfish with blood orange-ginger mostarda and blood orange dessert trio. Call Bricco at 617.248.6800 or Mare at 617.723.6273 to make reservations. The Blood Orange Extravaganza menu won’t be available on Valentine’s Day, so plan accordingly.
