Without diamonds, I appreciate that Indian paste (6)

I believe the answer is:

tahini

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

'paste' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for tahini that I've seen before include "Sesame-seed based foodstuff" , "Sesame seed paste" , "Sesame paste; in a hit (anag.)" , "Paste of sesame seeds" .)

I've seen this clue in The Independent.
