Lecturer as host, awfully sweet (9,5)
I believe the answer is:
charlotte russe
'sweet' is the definition.
(charlotte russe is a kind of sweet)
'lecturer as host awfully' is the wordplay.
'awfully' indicates an anagram.
'lecturer'+'as'+'host'='lecturerashost'
'lecturerashost' anagrammed gives 'CHARLOTTE RUSSE'.
(Other definitions for charlotte russe that I've seen before include "Sponge and custard pudding" , "Sponge/custard pudding" , "Lady's fingers cupping cream" , "dessert" , "dish" .)
