Make a suet pudding again: That's simple (7)

I believe the answer is:

austere

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

'that's simple' is the definition.
(I've seen this before)

'make a suet pudding again' is the wordplay.
'make' indicates an anagram.
'pudding again' becomes 're' (I can't justify this - if you can you should believe this answer much more).
'a'+'suet'='asuet'
'asuet' is an anagram of 'auste'.
'auste'+'re'='AUSTERE'

Can you help me to learn more?

(Other definitions for austere that I've seen before include "Grim - USA tree (anag)" , "Stark" , "Hard" , "Grim -- a US tree (anag)" , "not of luxury type" .)

I've seen this clue in the Evening Standard.
