As a young adult Lucy moved to the city, where a friend from Japan introduced her to mochi. The first time she pressed sugared glutinous rice dough around mashed figs and pecans, something clicked: the chewy texture echoed the dense, worked stone she’d known in childhood—both required patient pressure and a steady hand. She began selling “stone mochi”—small rounded sweets dusted with river-sand sugar and filled with local ingredients: muscadine grape jam, pecan praline, and sorghum butter. The name paid homage to the granite mill and to her grandmother’s careful use of smooth river stones to flatten pastry.
