With Indian dish, case for ordering cold water? (6,3)

Ross

I believe the answer is:

baltic sea

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

'water?' is the definition.
(I know that Baltic Sea is a sea)

'with indian dish case' is the wordplay.
'with' means one lot of letters goes inside another.
'indian' becomes 'balti' (I've seen this before).
'dish' indicates anagramming the letters (dish can informally mean to destroy).
'case' is an anagram of 'csea'.
'balti' inserted within 'csea' is 'BALTIC SEA'.

'for ordering cold' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for baltic sea that I've seen before include "Salt water" , "large amount of water" , "Water between Poland and Scandinavia" , "watery expanse" .)

I've seen this clue in The Telegraph.
