Boy reflected about hot Indian food (4)
I believe the answer is:
dahl
'indian food' is the definition.
'dahl' can be an answer for 'food' (dahl is a kind of food). I'm not certain of the 'indian' bit.
'boy reflected about hot' is the wordplay.
'boy' becomes 'lad' (informal term for boy).
'reflected' says the letters should be written backwards (letters reflected back).
'about' is an insertion indicator.
'hot' becomes 'h' (common abbreviation eg on taps).
'lad' in reverse letter order is 'dal'.
'dal' enclosing 'h' is 'DAHL'.
Can you help me to learn more?
(Other definitions for dahl that I've seen before include "Roald -, Br. author" , "Model" , "Roald or Sophie?" , "Indian dish of legumes and spices" , "'Roald ..., children's author (4)'" .)
