Forty years after he first put on a white apron, Abel Salgado remains an anomaly in the Jewish bakery world, but not for reasons one might expect. Sure, when he joined Local 453 of the Hebrew Master Bakers and Confectioners Union in 1963, the Chihuahua native was maybe the second or third Latino ever to join the union, then 2,000 strong. And even today, Salgado is one of the few non-Jews involved in the Jewish bakery business, a profession that occupies a particularly sacred — not to mention delicious — place in the religion. But, Salgado noted, ethnicity and theology were the least controversial issues when he originally applied to join the union.
