In Monty Python's The Meaning of Life, (1983), when the Maître d' is describing the jugged hare to Mr. Creosote, he says:
Ze hare is very high, and ze sauce is very rich with truffles, anchovies, Grand Marnier, bacon, and cream.
What is the meaning of "very high" in this context?
I found this reference in an 1885 cookbook online, but the precise meaning is still unclear:
If a hare is very high it may be left in tepid water for some little time; or if the blood has settled in one part, and it looks black, just cut it with the point of a knife, and soak it in warm water to draw out the dark blood.
The full clip is here.
