I remember going to a deli 30 years ago and getting something I think was called a sweet bagel. It wasn't the sort of fancy chocolate chip type bagel you see today. It had a very different texture. It was sort of the same shape, but the dough was skinny and had a big hole in it. The texture was dry and firm, but fairly tender when you bit into it. It had a very coarse crumb. It was slightly sweet, eggy (?), no flavor other than wheat flour, egg? and sweet. It may have been rolled in sesame seeds. I don't live near any delis now, does anyone know what these are called?
