Here's an idea for cooking with a new wok (1,4,4)

Ross

I believe the answer is:

i know what

'here's an idea' is the definition.
(both might be said before introducing a suggestion)

'cooking with a new wok' is the wordplay.
'cooking' is an anagram indicator (cook can mean to falsify or distort).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'with'+'a'+'n'+'wok'='withanwok'
'withanwok' anagrammed gives 'I KNOW WHAT'.

'for' is the link.

(Another definition for i know what that I've seen is " How about this".)

I've seen this clue in The Times.
