This is an interesting look at the bagel, from its invention in, apparently, Poland in the 14th century to its Americanzation in the late 20th century.
Of course, the story of the bagel is the story of Jews, from their struggles in Eastern Europe to their move into the New World.
Jews brought their food, and Yiddish language, with them mostly to New York. There, they grew their businesses, with unions and union-busting by Jews who made bagels and Jews who ran the bakeries.
By the '60s, the bread moves to the middle of the country and into the mainstream.
There's more to it than just a tasty treat, and it's worth it to read and find out more.
