A tasteful wobbler (5)
I believe the answer is:
jelly
'wobbler' is the definition.
(something which wobbles)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for jelly that I've seen before include "Semi-solid dessert" , "Wobbly food" , "Clear dessert" , "-- and ice cream" , "Semi-solid food" .)
