Sauce that's hot, while cold in boat, unfortunately (7)
I believe the answer is:
tabasco
'sauce that's hot' is the definition.
I know that 'hot' relates to this answer.
'while cold in boat unfortunately' is the wordplay.
'while' becomes 'as' (eg 'while I walked' means 'as I walked').
'cold' becomes 'C' (eg on taps).
'in' indicates putting letters inside.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'as'+'c'='asc'
'boat' anagrammed gives 'tabo'.
'asc' inserted within 'tabo' is 'TABASCO'.
Can you help me to learn more?
(Other definitions for tabasco that I've seen before include "Hot peppery sauce" , "Mexican state; pungent sauce" , "A hot spicy sauce" , "Hot red sauce" , "Mexico state" .)
