Why do we cook the traditional Chinese dish "pork knuckles and ginger stew" in a clay pot rather than a metal pot?

Use a large clay pot or a casserole (Don’t use cast iron or metal ones though, not suitable for cooking vinegar.)

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
