cook (n.) Look up cook at Dictionary.com
O.E. coc, from V.L. cocus "cook," from L. coquus, from coquere "to cook, prepare food, ripen, digest, turn over in the mind" from PIE base *pekw- "to cook" (cf. Oscan popina "kitchen," Skt. pakvah "cooked," Gk. peptein, Lith. kepti "to bake, roast," O.C.S. pecenu "roasted"). The noun was first; Gmc. languages had no one native term for all types of cooking. The verb is first attested late 14c.; the figurative sense of "to manipulate, falsify, doctor" is from 1630s. To cook with gas is 1930s jive talk.
"There is the proverb, the more cooks the worse potage." [Gascoigne, 1575]
