Run courses about adult salad ingredients (8)
I believe the answer is:
radishes
'salad ingredients' is the definition.
(I've seen this in another clue)
'run courses about adult' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'courses' becomes 'dishes' (as in courses in a meal).
'about' says to put letters next to each other.
'adult' becomes 'a' (abbreviation).
'dishes' put after 'a' is 'adishes'.
'r'+'adishes'='RADISHES'
(Other definitions for radishes that I've seen before include "salad plants" , "Fleshy roots for salads" , "Pungent fleshy edible roots" , "Pungent roots for salads" , "Salad vegetables" .)
