Land in trouble tucking into dodgy cure (7)
I believe the answer is:
ecuador
'land' is the definition.
(I know that Ecuador is a South American country)
'trouble tucking into dodgy cure' is the wordplay.
'trouble' becomes 'ado' (both can mean bother or commotion).
'tucking into' is an insertion indicator.
'dodgy' is an anagram indicator (a dodgy or wrong order of the letters).
'cure' with letters rearranged gives 'ecur'.
'ado' going inside 'ecur' is 'ECUADOR'.
'in' is the link.
(Other definitions for ecuador that I've seen before include "Where panama hats are made" , "South American republic" , "Is Cora due out in South America?" , "Quito's country" , "Land" .)
