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

'extremely sharp odd taste in middle of fruitcake' is the definition.
I can't tell whether this definition defines the answer.

'odd taste in middle of fruitcake' is the wordplay.
'odd' indicates anagramming the letters.
'middle of' says to take the centre.
The central letter of 'fruitcake' is 't'.
'taste'+'in'='tastein'
'tastein' is an anagram of 'natties'.
'natties'+'t'='NATTIEST'

Can you help me to learn more?
