Order drinks regularly, tasteless stuff (6)

I believe the answer is:

diktat

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

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

'drinks regularly tasteless stuff' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'tasteless stuff' becomes 'tat' (I have seen 'Shoddy stuff' mean 'tat' so perhaps 'stuff' could also mean 'tat'. I am not sure about the 'tasteless' bit.**).
The alternate letters of 'drinks' are 'dik'.
'dik'+'tat'='DIKTAT'

Can you help me to learn more?

(Other definitions for diktat that I've seen before include "Categorical statement" , "Official order" , "arbitrary order" , "Harsh order or decree" , "Declaration allowing no opposition" .)

I've seen this clue in The Times.
