Make me a blend that could be made better (8)

'could be made better' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'make me a blend' is the wordplay.
I cannot quite understand how this works, but
'me' is present in the answer.
'a' is found in the answer.
an anagram of 'blend' is 'ndble' which is located in the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).

'that' acts as a link.

Can you help me to learn more?
