Black skate cooked for picnic hamper (6)
I believe the answer is:
basket
'picnic hamper' is the definition.
'basket' can be an answer for 'hamper' (I've seen this in another clue). I am not sure about the 'picnic' bit.
'black skate cooked' is the wordplay.
'black' becomes 'b' (as in pencil classifications).
'cooked' is an anagram indicator (letters cooked into a new form).
'skate' with letters rearranged gives 'asket'.
'b'+'asket'='BASKET'
'for' is the link.
Can you help me to learn more?
(Other definitions for basket that I've seen before include "''Don't put all your eggs in one . . . . . .''" , "Wicker carrier" , "Container made of interwoven cane or wire" , "Woven container for carrying food etc" , "Container with handles" .)
