Flavour comes back somewhat similar to an egg (4)
I believe the answer is:
oval
'similar to an egg' is the definition.
I can't judge whether this definition defines the answer.
'flavour comes back somewhat' is the wordplay.
'somewhat' indicates a hidden word.
'comes back' shows that the letters should be reversed in order.
'lavo' can be found hidden inside 'flavour'.
'lavo' in reverse letter order is 'OVAL'.
Can you help me to learn more?
(Other definitions for oval that I've seen before include "Ellipse" , "Curved shape" , "Ellipsoidal" , "Rounded like an egg" , "Elliptical figure" .)
