My mother's Manhattan clam chowder was nothing more than her oxtail vegetable soup, with institutional sized cans of chopped clams and clam broth dumped in. Seemed to be popular at neighbourhood pot lucks. One of the neighbours managed a credit department at a Buffalo industrial distributor, and he hired my mother to make an industrial sized batch for an annual 'thank you' dinner for his staff. 'Crazy Anna the Chowder Vendor' we called her. Not to her, of course. I would be dead! 😵
