Friedrich Christian Accum,
Culinary Chemistry
“ A kitchen is, in fact, a chemical laboratory; the boilers, stew-pans, and cradle spit of the cook, correspond to the digestors, the evaporating basins, and the crucibles of the chemist. And numerous as the receipts of cookery are, the general operations (like the general process of chemistry) are but few. In some the object aimed at is, to extract the constituent parts of the food, so as to exhibit them in a separate state, or to combine them with other substances, to produce new compounds which differ widely from those from which they originated. ”
