Powder used in macrobiotic latte coming from the East (4)
I believe the answer is:
talc
'powder' is the definition.
(talcing is a kind of powdering)
'in macrobiotic latte coming from the east' is the wordplay.
'in' indicates the answer is hidden within the clue.
'from the east' says the letters should be written in reverse.
'clat' is hidden within 'macrobiotic latte coming'.
'clat' in reverse letter order is 'TALC'.
'used' is the link.
(Other definitions for talc that I've seen before include "Cosmetic powder" , "soother" , "Magnesium silicate powder" , "(Mineral providing) powder" , "Powder used as toiletry" .)
