The Free On-line Dictionary of Computing (19 January 2023):
cooked mode
The normal character-input mode of a Unix
terminal device: with interrupts enabled and with erase,
kill and other special-character interpretations performed
directly by the tty driver. Opposite of raw mode. See
also rare mode.
Other operating systems often have similar mode distinctions,
and the raw/rare/cooked way of describing them has spread
widely along with the C language and other Unix exports.
Most generally, "cooked mode" may refer to any mode of a
system that does extensive preprocessing before presenting
data to a program.

n.
[Unix, by opposition from raw mode] The normal character-input mode, with
interrupts enabled and with erase, kill and other special-character
interpretations performed directly by the tty driver. Oppose raw mode,
rare mode. This term is techspeak under Unix but jargon elsewhere; other
operating systems often have similar mode distinctions, and the raw/rare/
cooked way of describing them has spread widely along with the C language
and other Unix exports. Most generally, cooked mode may refer to any mode
of a system that does extensive preprocessing before presenting data to a
program.
