Who might steal eggs — and slowly cook them? (7)
I believe the answer is:
poacher
'who might steal eggs' is the definition.
(a poacher might steal eggs from the wild)
'slowly cook them?' is the wordplay.
I cannot quite understand how this works, but
'cook' could be 'poach' (poaching is a kind of cooking) and 'poach' is present in the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for poacher that I've seen before include "Gamekeeper's opponent" , "criminal" , "Stealer of game" , "in the kitchen?" , "Cooking device" .)
