Read before attempting: https://newyorkerbagels.com/bagel-safety-dont-be-an-er-stati... Seriously. As any nurse about a "bagel injury" and they will know exactly what you are talking about. It is so common that it is addressed in some military first aid courses.

Bagel topology experiments preferred over human topology ones.

Having grown up in a non bagel rich country, I've been puzzled ever since I first encountered them. What's the point of the weird shape? What's wrong with a square or even circular piece of bread without an inconvenient hole in the middle? For an outside viewer, it looks like someone went out of their way to create a shape that makes it as difficult to deal with as possible, and then mass psychosis took over and ever…

the uniform shape helps ensure even heat transfer for when they are cooked in boiling water (to which is added baking soda), and baked evenly in an oven.

(in case you are wondering why they are boiled, it's to develop a chewy crust)

This method doesn't always leave the bagel looking aesthetically pleasing. The bagel, even in the linked video linked in the article, appears to have been hacked apart by a machete wielding attacker, leaving tufts of bread falling out. There is another way! To do so, cut the bagel just one time (not four), turning the knife around the bagel until the bagel is 180 degrees flipped when the knife returns to the starting…

I thought the first photo was an example of a failed bagel slicing attempt, until I started reading the article.

It's not for the oven, it's for when they boil in water.

A proper bagel is boiled first, then baked.

It's also used for transportation and display by threading a rod or string through the hole, but the main reason is for even boiling. Same as a doughnut (except that is boiled in oil).

Ah. That makes sense. Thanks for the answer :)

Still, I eat plenty of bread that's non bagel shaped and fairly evenly baked. I guess I pay slightly more for the more difficult production process then, or have to suffer bread that's just not quite as perfectly uniform in texture as it could be. Well worth it, if you ask me, to not have to deal with the frustrating shape. Mileages vary, of course :)

I, too, kind of share your perspective, and indeed prefer the texture and structure of non-bagels to bagels. I just find them unnecessary and harder to put fun fillings inside them.

> 0.24% chance of being one of those people injured, each day 2,000 / 330,000,000 / 365 = 0.00000166% chance of daily bagel injury. Not sure what calculation you did, but as far as I can tell it is off by 5 orders of magnitude.

(2000 / (300000000 / 365)) * 100 You seem to have forgotten to move the decimal place to get a percentage.

It seems the original source for all the TIL sites is a WSJ article which wrote that in 2008 there were 1979 people who went to the ER due to bagel related injuries. So it's not 2000 per day, it's per year.

Keep in mind that when a HN user writes things like "seriously", "ask any x", "it's so common". It means they probably don't know what they're talking about.

Although this is not a definite answer I think it makes sense, that the inconvenient hole actually provide a convenient storage solution, historically at least.

I really hope this isn’t really that common. Like how bad do you have to be with a knife and do you really need someone to tell you it’s going to be a tad difficult to cut a frozen piece of bread? Basic safety tip: Don’t pull or point pointy bits towards your meaty bits.

Seriously, the worst cut I have had has been when cutting a loaf of bread with the wrong knife. It was a fresh loaf as well. Cut half into one finger tip and a sliced a piece off the tip of another. It just takes one moment of frustrated bread-doesn't-cut-wrangling and a slip. My lesson from it: buy a serrated bread knife instead of trying to make do with whatever is in the at the time super minimal kitchen drawer. S…

My worst kitchen accident happened cutting bread too. I was trying to cut through a stale loaf using a (brand new!) serrated knife, got lost in thought for one second, and the knife slipped of the bread and into the tip of my finger. Seriously debated going to the urgent care, and took months for feeling to return in the tip.

My takeaway was to be vigilant at being 100% focused whenever using knives.
