here is something I found very interesting about these bagels.-----Famous Obwarzanki from Kraków, which were also known as "bajgle" before the war, are a traditional Hebrew snack which is served on a Jewish holiday called Shavuot. Traditional bagel is sprinkled with poppy-seeds. Today, sellers offer a whole variety of them; apart from poppy-seed there are also sesame seed, rock salt and even pizza sprinkles.
