Edible seaweed from best part of shore I miss in confusion (5,4)
I believe the answer is:
irish moss
'edible seaweed' is the definition.
(I've seen this before)
'best part of shore i miss in confusion' is the wordplay.
I cannot quite understand how this works, but
'part' could be 'iris' (iris is a kind of part) and 'iris' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for irish moss that I've seen before include "Edible seaweed, carrageen" , "Edible red seaweed" .)
