Brusamolin, very rare, is typically Venetian from Padua and from Piazzola sul Brenta in Padua, with a very small stock also in Vicenza in Vicenza and in Torri di Quartesolo, Brusamolini is practically unique and should be due to an incorrect transcription of the previous one, Brusamolino it is specific of the Milanese, of Inzago, Cassano d'Adda, MIlano, Melzo and Pozzuolo Martesana, they should derive from nicknames based on the Lombard and Veneto brusa (burn, but also marinate, temporarily abandon), much more probably based on the second meaning , implying perhaps in a joking way that the progenitors were not great workers.
