I crave a cocktail - it's pure greed (7)

I believe the answer is:

avarice

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

'pure greed' is the definition.
'avarice' can be an answer for 'greed' (avarice is a kind of greed). I'm not sure about the 'pure' bit.

'i crave a cocktail' is the wordplay.
'cocktail' is an anagram indicator.
'i'+'crave'+'a'='icravea'
'icravea' is an anagram of 'AVARICE'.

'it's' is the link.

Can you help me to learn more?

(Other definitions for avarice that I've seen before include "Stinginess" , "Insatiable lust" , "Wanting to be rich" , "Rapacity" , "Greed for gain" .)

I've seen this clue in The Irish Times.
