Gelatinous dessert (10)
I believe the answer is:
blancmange
(Other definitions for blancmange that I've seen before include "Table cream" , "Almond-flavoured jelly-like milk pudding" , "Pudding made with milk - ABC man, Glen (anag)" , "Dessert of flavoured milk stiffened with cornflower" , "Mouldy food" .)
