Description
Alkaline boiling gelatinizes starch and denatures proteins for a glossy, chewy crust.
Technical
Sodium hydroxide (lye) or sodium bicarbonate solution raises pH to ~11-12, accelerating Maillard reactions while limiting gelatinization temperature. This creates a pectin gel network reinforced with cross-linked proteins.
Culinary Significance
Essential for authentic bagel texture - produces shiny crust with distinct 'snap' and extended shelf life through moisture regulation.
