Very good at baking? (3)
I believe the answer is:
hot
'baking?' is the definition.
(similar in meaning)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hot that I've seen before include "Flaming - stolen" , "Having a high temperature" , "(Of food) spicy" , "Spicy or very warm" , "Sultry or angry" .)
