Securing string round cooked lamb dish (7)
I believe the answer is:
timbale
'dish' is the definition.
(timbale is a kind of dish)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for timbale that I've seen before include "Minced meat dish" , "pastry dish" , "mould in kitchen" , "Dish cooked in a mould" .)
