Clue: Mean to keep recipe for such poor-quality meat (7)
Answer: STRINGY
Explanation: Definition: such poor-quality meat
An envelope ('to keep') of R ('recipe') in STINGY ('mean'). The definition is problematical, in that on the face of it, STRINGY is an adjective, and the underlined portion of the clue seems to indicate a noun. Is the intention that STRINGY should be read as a noun, on the lines of "streaky" for streaky bacon? If so, I cannot trace any justification for this use. Or is 'such' intended to indicate an adjective? A similar use seems to be in play in 4D; I find it less objectionable there, but they are both rather woolly.
