Stale bread is key for making french toast because the dry, stale bread absorbs the egg solution much more and normal bread would fall apart in our hands. Stale bread is a key ingredient but how does bread turn stale? Another key ingredient are eggs which gives us flavor and taste of the french toast. Once the bread is dipped and placed on the skillet, how does a raw egg-- a liquid, turn into a fried, cooked egg-- a solid, in the french toast? Speaking of cooking, how does one know how long to cook something? How long is the best time to cook french toast based on what recipes say or suggest? Don’t you hate it when you want to save your sandwich for later so you leave it on your table, but when you come back to it the bread is rock hard. So many people throw away stale bread and waste bread that has turn …show more content…

How does that same chemical reaction happen in eggs? Eggs whites have proteins called “globular proteins” which is a long protein molecule that is twisted, curled up, and folded in no specific shape. There are varieties of “weak chemical bonds” that keep the protein in that twisted, folded, shape so it drifts in the “water” that it is surrounded by. Just like how gas particles react when heat is applied, the eggs-white proteins act the exact same way. They begin to bounce around really fast and bump into other particles around them, like water. All the bumping breaks the weak bonds that once kept the proteins curled up, resulting in the egg proteins uncurling and bump into other uncurled proteins, forming a new chemical bond. The chemical bond creates a web of connected proteins where the water particles dispersed throughout the web, which is when the egg has turned into a solid/semi-solid. Overcooking the egg causes more bonds to form and less space for water, eventually the water will evaporate which causes the egg protein to become turn into a
