A menu or formula to attract strongly... (7)
I believe the answer is:
enamour
'attract strongly' is the definition.
'enamour' can be an answer for 'attract' (enamouring is a kind of attracting). I'm not sure about the 'strongly' bit.
'a menu or formula' is the wordplay.
'formula' is an anagram indicator (the letters are the ingredients or formula).
'a'+'menu'+'or'='amenuor'
'amenuor' anagrammed gives 'ENAMOUR'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for enamour that I've seen before include "entrance" , "sweep one off one's feet" , "Charm, captivate" , "Our name (anag)" , "Fill with love" .)
