Today is a national holiday in many countries in celebration of the Christian holy day of Good Friday, which precedes Easter. Coincidently, today the Jewish people also celebrate Passover. In Brazil, the Catholic families of Portuguese ancestry (like mine) gather to eat a fish dish (bacalhoada) and, coincidently, so do the Jewish families (gefilte fish). Both peoples have adopted their ancestors’ customs to the ingredients they could find in the host country that resembles the original ingredients. This is an example of natural “localization,” in the pre-globalized world, of the old rituals to the new environment. Happy Easter and Happy Passover to all of you who celebrate these holidays.
