It follows higher course to start with? (4)
I believe the answer is:
soup
'course to start with?' is the definition.
'it follows higher' is the wordplay.
'it follows' becomes 'so'.
'higher' becomes 'up'.
'so'+'up'='SOUP'
(Other definitions for soup that I've seen before include "See 19" , "Stolen plate melted down" , "Bisque, for example" , "Eg, mulligatawny" , "Eskimo people" .)
