Food that epicure recommends if you are kept indoors at first (8)
I believe the answer is:
teriyaki
'food' is the definition.
(teriyaki is a kind of food)
'that epicure recommends if you are kept indoors at first' is the wordplay.
'that epicure' becomes 'te' (this could be a standard abbreviation I've not previously seen).
'at first' indicates taking the first letters.
The initial letters of 'recommends if you are kept indoors' is 'riyaki'.
'te'+'riyaki'='TERIYAKI'
Can you help me to learn more?
(Other definitions for teriyaki that I've seen before include "Japanese dish of beef, chicken or seafood, marinated in soy sauce" , "Basted and broiled" , "Japanese cooking using sweet soy sauce" , "Japanese dish of cooked meat or seafood, marinated in soy sauce" , "Oriental food" .)
