Bagel: History of a bread with a hole
06.06.2026 , ZKM Vortragssaal
Sprache: English

Bagels are bread rolls with a hole, or pretzels with fewer holes, and are wonderful baked goods. Whether they are served with cream cheese and lox or hummus, there is probably nothing better than a fresh bagel. But did you know that bagels have a truly interesting history? From medieval German monasteries to Poland, and from the Jewish diaspora in New York and Montréal.

So in this talk, I'll be covering the important questions of our time: Where does the Bagel come from? Where do you get the best Bagels (Montréal or New York)? And how do all these doughnuts with rigor mortis differ? And of course, you'll learn how to bake a proper bagel.

Come by and learn more than you ever wanted to know about Bagels, after you hopefully ate a delicious Bagel at the WOC (from 12 am to 3 pm).
