I believe the answer is:

zinc bloom

I'm a little stuck... Click here to teach me more about this clue!

'compound' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'zulu out to capture cape' is the wordplay.
'zulu' becomes 'Z' (phonetic alphabet: alpha, bravo, charlie etc.).
'out to' becomes 'inbloom' (I can't explain this - if you can you should believe this answer much more).
'capture' is an insertion indicator.
'cape' becomes 'c' (abbreviation used on maps).
'inbloom' enclosing 'c' is 'incbloom'.
'z'+'incbloom'='ZINC-BLOOM'
