Why cheese melts, bread browns and sandwiches go soggy, explained from the chemistry and the sources.
Sodium Citrate and Smooth Melted Cheese: How the Salt Works
Sodium citrate binds calcium in casein so cheese melts without breaking. Sources on the 1911 origin, the 3 percent legal cap and home sauce ratios.
Why Sandwiches Get Soggy: Moisture, Bread and Barriers
Sandwiches turn soggy when water moves from wet fillings into bread. Sources on water activity, lettuce, tomato, fat barriers, toasting and packaged sandwiches.
The Maillard Reaction and Why Bread Browns
Bread browns when sugars and amino acids react on a hot, dry surface. Sources on Maillard and Hodge, crust formation, toast chemistry and caramelization.
Why Cheese Melts and Why Some Cheese Turns Greasy
Cheese melts when heat loosens its casein network and turns greasy when the network collapses. Sources on acid, calcium, age and why oil separates.
