Extreme gluttony, eating hard marrow - taste pungent? (8)

I believe the answer is:

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

'pungent?' is the definition.
('garlicky' can be similar in meaning to 'pungent')

'extreme gluttony eating hard marrow taste' is the wordplay.
I cannot really see how this works, but
'taste' could be 'lick' (I've seen this before) and 'lick' is located in the answer.
The remaining letters 'gary' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for garlicky that I've seen before include "tasting of cloves?", "Strong-smelling", "Likely to cause bad breath when eaten?", "somewhat pungent".)

I've seen this clue in Sydney Morning Herald.
