Preparation for guy or Tibetan leader - food made from curdled milk (6)
I believe the answer is:
yogurt
'milk' is the definition.
(thesaurus)
'preparation for guy or tibetan leader food made from curdled' is the wordplay.
I cannot really understand how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
an anagram of 'guy' is 'ygu' which is within the left over letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for yogurt that I've seen before include "Grouty (anag.)" , "Cultured fare" , "Milk-food" , "Food made from milk thickened with bacteria" , "Food made from fermented milk" .)
