What You Need to Know
The baguette undergoes a Maillard reaction at 140–165 °C, forming melanoidins that give a caramelized crust. Pickled vegetables are acidified with acetic acid and salted to penetrate the cell walls, while mayonnaise is stabilized by phospholipids and a low pH that prevents coalescence.
