Boiling is the step that makes a bagel a bagel. These machines kettle and scald the rings before they bake, so the crust sets glossy and the crumb stays chewy — gas or electric, sized from a deli counter up to a production line.
The scald gelatinizes the starch on the surface before it hits the oven — that is what sets a glossy, chewy crust; skip it and you have bread rings.
Gas recovers temperature faster between batches, which matters at volume; an electric bagel machine installs anywhere with the power and needs no flue. Tell us your batch size and we'll advise.
Yes — the kettles double as boiling baths for pretzels, noodles and dumplings; same scald, different product.
A bagel forming machine rolls and joins the ring; a bagel boiling machine does the kettling step that makes it a bagel rather than a bread roll. Skipping the second one is why so many café bagels taste like rolls.
