Tasty and cooked so hot in volume (9)
I believe the answer is:
toothsome
'tasty' is the definition.
(toothsome can mean tasty or delicious)
'cooked so hot in volume' is the wordplay.
'cooked' indicates an anagram.
'in' is an insertion indicator.
'volume' becomes 'tome' (a tome is a large or heavy book).
'so'+'hot'='sohot'
'sohot' anagrammed gives 'ooths'.
'ooths' put inside 'tome' is 'TOOTHSOME'.
'and' is the link.
(Other definitions for toothsome that I've seen before include "Pleasing" , "Temptingly tasty" , "Appetising" , "attractive" , "It's just like a T-Rex" .)
