'nettles' is the definition.
The answer and definition can be both to do with human feelings as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?

'question found in cooked food' is the wordplay.
'question' becomes 'qu'.
'found in' indicates putting letters inside.
'cooked food' becomes 'pies' (I've seen this before. I am not sure about the 'cooked' bit.**).
'qu' placed into 'pies' is 'PIQUES'.

'in' acts as a link.
