Cake seen first in tortellini (5)
I believe the answer is:
torte
'cake' is the definition.
(torte is a kind of cake)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for torte that I've seen before include "Rich (Austrian) cake or pastry" , "Rich sweet cake" , "Sweet cake (from Ger.)" , "(Austrian) cake with cream and fruit or nuts" , "Rich food" .)
