That lady cooks cakes, given hot tip (9)
I believe the answer is:
baksheesh
'tip' is the definition.
(Persian word for a tip or donation)
'that lady cooks cakes given hot' is the wordplay.
'that lady' becomes 'she' ('she' refers to a woman).
'cooks' becomes 'bakes' (baking is a kind of cooking).
'cakes' is an insertion indicator (cake can mean to cover).
'given hot' becomes 'h' (abbreviation, eg on taps. I am not sure about the 'given' bit.).
'she' inserted inside 'bakes' is 'bakshees'.
'bakshees'+'h'='BAKSHEESH'
Can you help me to learn more?
(Other definitions for baksheesh that I've seen before include "Gratuity or tip in Middle East" , "(Oriental) money given as a tip or alms" , "Small amount given for services rendered" , "Gift of money" .)
