Picnic baskets (7)
I believe the answer is:
hampers
'picnic baskets' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hampers that I've seen before include "Delays with food baskets" , "Encumbers" , "Large baskets; hinders" , "Obstructs with picnic baskets" , "picnic containers" .)
