King Charles not favoured — no turning back — one in the soup? (7)

Ross

I believe the answer is:

crouton

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

'back one in the soup?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'king charles not favoured no turning' is the wordplay.
'king charles' becomes 'cr' (I've seen this in other clues).
'not favoured' becomes 'out' (I've seen this before).
'turning' shows that the letters should be reversed in order.
'no' backwards is 'on'.
'cr'+'out'+'on'='CROUTON'

Can you help me to learn more?

(Other definitions for crouton that I've seen before include "Piece of fried bread for garnishing" , "Small piece of toasted bread in soup or salad" , "Bit of toast in soup" , "Fried garnish for soup" , "Small cube of fried bread" .)
