Years ago, I went on a food walking tour of East Williamsburg, and one of their stops was Tedone Latticini, where Georgie Tedone DiPalma, the "Mozzarella Lady", had been making mozzarella at her family's store for literally decades. She made some right in front of us, and she advised/warned us that we'd have to eat it that day or it wouldn't be good anymore. She's long since passed away.
