Having an oddly slaty taste? (5)

I believe the answer is:

salty

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

'having an oddly' is the definition.
I can't tell whether this definition defines the answer.

'slaty taste?' is the wordplay.
'slaty' can be anagrammed to 'SALTY'.
However, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for salty that I've seen before include "Brackish" , "Saline" , "Sharp (language, humour)" , "Engagingly stimulating or provocative" , "Piquant" .)

I've seen this clue in the Evening Standard.
