Kosher crossovers?

To what extent are bagels and challah becoming universal foods? Just another, well, food for thought here...

A Dominican bakery on Broadway near 228th Street in Marble Hill has "rogalitos" - rugelach.

A Colombian bakery on 37th Avenue in Jackson Heights sells "pan de challah."

A Mexican market on Roosevelt Avenue has, in neon, the words "tamales, tacos, bagels."

A trend?

Next time I'll get pictures!
