Bagels, lox and cup tea which would be sipped from a saucer. It was never "a cup of tea" but just "nice cup tea." I was brought up in a jewish neighborhood with many of my acquaintances from Eastern Europe after WWII. At the time we lumped them all together and called them "DPs" meaning displaced persons. I'd have way to much to mention of their culture and foods if I started, so I won't . Even though they were from different areas, they still could converse in Yiddish, that was their own specially (secret) developed language.
I remember my step-grandfather giving me bagels, cream cheese and lox. Had to be bought fresh and only from a certain deli. One of the best memories I have.
