Bagel and lox is a classic New Yorker sandwich consisting of a freshly baked bagel that's split in half, then topped with cream cheese and cured salmon. The sandwich can be additionally garnished with capers or thinly sliced red onions, while the plain cream cheese can be replaced with dill and chive cream cheeses.
Both the bagels and lox were introduced to America by European Jewish immigrants at the turn of the 20th century, and by the 1950s, the bagel became a staple food in America. Traditionally, they could be found at New York's Jewish delis, but today they're available throughout the country.
