I believe the answer is:

eggplant

I'm a little stuck... Click here to teach me more about this clue!

'in food' is the definition.
'eggplant' can be an answer for 'food' (eggplant is a kind of food). I am not certain of the 'in' bit.

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for eggplant that I've seen before include "Vegetable" , "US name for aubergine" , "Another word for aubergine" , "What goes into moussaka" , "Its fruit is aubergine" .)

I've seen this clue in the Evening Standard.
