Nail in food (4)

Ross

I believe the answer is:

tack

This clue is a double definition.

'nail' is the first definition.
(I know that tack is a type of tack)

'food' is the second definition.
(I've seen this before)

'in' is the link.

(Other definitions for tack that I've seen before include "Small broad-headed nail" , "fix > riding gear" , "Rubbishy things" , "Small nail; sail (boat) against the wind" , "Turn and sail into the wind" .)

I've seen this clue in The Telegraph.
