Shallot relatives (5)
I believe the answer is:
leeks
'shallot relatives' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for leeks that I've seen before include "Emblems of 19" , "Vichyssoise ingredient" , "Welsh vegetables?" , "Vegetables - keels (anag)" , "Scallions" .)
