Lamb possibly? Try it without sauce initially (8)
I believe the answer is:
essayist
'lamb possibly?' is the definition.
(I know that Charles Lamb is a essayist)
'try it without sauce initially' is the wordplay.
'try' becomes 'essay' (essay can mean to try or attempt something).
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'initially' says to take the initial letters.
The initial letter of 'sauce' is 's'.
'it' placed around 's' is 'ist'.
'essay'+'ist'='ESSAYIST'
(Other definitions for essayist that I've seen before include "Lamb, perhaps" , "Writer of little prose pieces" , "One who writes short pieces on given subject" , "Writer of short compositions" , "Writer such as Addison" .)
