It’s food, clot! (4)

I believe the answer is:

cake

I believe this clue is a double definition.

'it's food' is the first definition.
(cake is a kind of food)

'clot' is the second definition.
(thesaurus)

(Other definitions for cake that I've seen before include "You can't eat it and have it" , "Item of food or soap" , "Eg, gateau" , "Confectionery" , "Mixture of flour, sugar, eggs and fat" .)

I've seen this clue in the Evening Standard.
