The real world etymology of the proverb is unclear, but the first known verified variant thereof had already turned up in the French early-1840s six-volume novel
by Eugène Sue, which read "
Et puis la vengeance
se mange très-bien froide
, comme on dit vulgairement
" (Oeuvres complètes, Vol. 3, p. 53, 1841 ), or " 
And then revenge is
very good eaten cold
, as the vulgar say
", according to the 1846 two-volume translation in English as
The Orphan; Or, Memoirs of Matilda
( ;  ISBN 9781145991941 – 2010 facsimile reprint), which incidentally also constituted the first known verified usage of the proverb in English. Since Sue had italicized the "se mange très-bien froide" part – faithfully adhered to in the 1846 English translation (p. 303) – , this implied that an older colloquial version had existed previously. As exactly phrased by Khan though, actually appears to have been first used as such in the 1982
