Fat Eleanor emptied food store (6)
I believe the answer is:
larder
'food store' is the definition.
(I've seen this before)
'fat eleanor emptied' is the wordplay.
'fat' becomes 'lard' (lard is a kind of fat).
'emptied' suggests removing the centre.
'eleanor' with its centre taken out is 'er'.
'lard'+'er'='LARDER'
(Other definitions for larder that I've seen before include "Stock of provisions" , "Place where food is kept" , "Store cupboard" , "Small room for storing food" , "Room or cupboard for food storage" .)
