Father detects eels, oddly, as note in Spanish dish (6)
I believe the answer is:
paella
'spanish dish' is the definition.
(paella is a type of Spanish dish)
'father detects eels oddly as note' is the wordplay.
I cannot quite understand how this works, but
'father' could be 'pa' (pa can mean dad or father) and 'pa' is found in the answer.
'note' could be 'la' (musical note as in do-re-mi) and 'la' is present in the answer.
The remaining letters 'el' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for paella that I've seen before include "Spanish dish based on saffron rice" , "something to eat" , "Spanish dish of rice, meat and seafood" , "Spanish dish of rice, shellfish, etc" , "Fare for Spaniard" .)
