Etymology
borrowed from French, going back to Old French galatine, galentine "sauce made from jellied fish or meat broth," from galat-, galent- (probably going back to Latin gelātus, past participle of gelāre "to freeze, congeal") + -ine -ine entry 2; in earlier sense "meat or fish sauce" going back to Middle English galentyn, borrowed from Middle French — more at cold entry 1
Note: Neither the intrusive -n- nor the change of initial syllable from ge- to ga- in the Old French forms is easily explained. The hypothesis that the word is borrowed from the vernacular Dalmatian of Dubrovnik (Ragusa) is very tenuous, given that the word is only attested there three centuries after its first appearance in French.
