Kettle Boiling: Why Bagels Are Boiled Before Baking
Kettle boiling changes the bagel surface before baking, helping create chew, shine, crust, and the eating experience people expect from traditional bagels.
What boiling changes
| Change | Result In The Bagel |
| Surface starch gelatinization | Helps set the crust and create a distinctive exterior. |
| Shape stability | The bagel holds form before entering high oven heat. |
| Chew | Boiling contributes to the firm, chewy bite associated with classic bagels. |
| Color and shine | Boil water ingredients and baking conditions can affect browning and surface appearance. |
