Liqueur recalled: first rate, rich — a tip for dinner! (7)
I believe the answer is:
ratafia
'liqueur' is the definition.
(I know that ratafia is a type of liqueur)
'recalled first rate rich a tip for dinner' is the wordplay.
'recalled' says the letters should be written in reverse.
'first rate' becomes 'AI' (resembles A1, old-fashioned slang for very good).
'rich' becomes 'fat' (rich can describe fat or creamy food).
'tip for' indicates one should take the final letters.
The last letter of 'dinner' is 'r'.
'ai'+'fat'+'a'+'r'='aifatar'
'aifatar' written backwards gives 'RATAFIA'.
(Other definitions for ratafia that I've seen before include "Brandy liqueur with almonds or peach, apricot or cherry kernels" , "Almond biscuit/liqueur" , "Cordial" , "Almond liqueur, biscuit" , "Biscuits" .)
