Dish kind of spicy ends scare (7)

I believe the answer is:

petrify

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

'scare' is the definition.
(thesaurus)

'dish kind of spicy ends' is the wordplay.
'dish kind' becomes 'petri' (I can't explain this - if you can you should believe this answer much more).
'ends' indicates one should take the final letters.
The final letters of 'of spicy' are 'fy'.
'petri'+'fy'='PETRIFY'

Can you help me to learn more?

(Other definitions for petrify that I've seen before include "Turn to stone" , "Frighten stiff" , "Paralyse with fear" , "Scare stiff" .)

I've seen this clue in The Daily Express.
