Caviar

Caviar , noun

[French caviar, from Italian caviale, from Turkish Havīār.]

The roes of the sturgeon, prepared and salted; -- used as a relish, esp. in Russia.

Caviare was considered a delicacy, by some, in Shakespeare's time, but was not relished by most. Hence Hamlet says of a certain play. “'T was caviare to the general,” i. e., above the taste of the common people.
