Cut across road following flag's course (5,4)
I believe the answer is:
irish stew
'course' is the definition.
(type of meal)
'cut across road following flag's' is the wordplay.
I cannot really see how this works, but
'road' could be 'st' and 'st' is present in the answer.
'cut' could be 'hew' (hew can mean to chop or cut) and 'hew' is present in the leftover letters.
'flag's' could be 'iris' ('iris' can be a synonym of 'flag') and 'iris' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for irish stew that I've seen before include "food" , "National dish, boiled mutton, spuds and onions" , "Mutton/onion/potato dish" , "Local dish of meat, potatoes and onions" , "Mutton and vegetable dish" .)
