"Ostosh and her partner Renata Fernández Domínguez launched Madre Masa in 2022 to offer their community tortillas using nixtamalized corn grown in western Michigan. They nixtamalize and stone-grind organic blue dent or yellow Wapsie Valley corn using a countertop molinito — an electric mill equipped with volcanic basalt rock. Each Friday, they transform their home kitchen into a makeshift tortilleria and sell packages of fresh tortillas and masa." - Serena Maria Daniels
