I believe the answer is:

pekoe

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

'tea' is the definition.
(I know that pekoe is a tea)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for pekoe that I've seen before include "Variety of black tea" , "brew" , "Thin mark; run naked" , "Scented black tea" , "High quality black tea" .)

I've seen this clue in the Sydney Morning Herald.
