Girl consuming second starchy pudding (8)
I believe the answer is:
semolina
'starchy pudding' is the definition.
'semolina' can be an answer for 'pudding' (I've seen this before). I am unsure of the 'starchy' bit.
'girl consuming second' is the wordplay.
'girl' becomes 'selina' ().
'consuming' is an insertion indicator.
'second' becomes 'mo' (both are short periods of time).
'selina' placed around 'mo' is 'SEMOLINA'.
Can you help me to learn more?
(Other definitions for semolina that I've seen before include "Pudding flour" , "Hard grains of wheat in puddings and pasta" , "Hard particles of wheat used in puddings etc" , "Milled wheat product" , "pudding ingredient" .)
