This pizzeria has a hefty lineup of weekly contributions by guest restaurants to add uncommon touches to their pies. This week (through Thursday) there’ll be anchovies, potato chips and Basque Garrotxa cheese from Eel Bar; and next week (Feb. 3 through 5), Adda will add ground lamb and fresh mint for one option and white korma sauce with braised short rib, Fontina, chiles and cilantro for another. Leon’s, Ernesto’s, Bartolo, Hags, Virginia’s and Golden Hof are some others lined up, through March 26.
