Spirit tipsy chefs must have included (6)

I believe the answer is:

psyche

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

'spirit' is the definition.
(psyche can mean spirit or soul)

'tipsy chefs must have included' is the wordplay.
'PSYCHE' is hidden within the letters.
But, I'm not sure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for psyche that I've seen before include "Soul - girl from Greek mythology" , "Human faculty for thought - Cupid's lover" , "The soul, spirit or mind" , "Human soul or spirit" , "A beautiful girl" .)

I've seen this clue in The Sunday Times and The Times.
