Get very hot regularly in Black Sea (4)
I believe the answer is:
bake
'get very hot' is the definition.
I can't judge whether this definition defines the answer.
'regularly in black sea' is the wordplay.
'regularly in' means one should take alternating letters.
'black'+'sea'='blacksea'
The alternating letters of 'blacksea' are 'BAKE'.
Can you help me to learn more?
(Other definitions for bake that I've seen before include "Oven-cook" , "Biscuit" , "Cook in a hot oven" , "Cook (cakes, etc)" , "Cook cake or bread" .)
