Mixed my one Asian sauce (10)
I believe the answer is:
mayonnaise
'sauce' is the definition.
(I know that mayonnaise is a type of sauce)
'mixed my one asian' is the wordplay.
'mixed' is an anagram indicator.
'my'+'one'+'asian'='myoneasian'
'myoneasian' is an anagram of 'MAYONNAISE'.
(Other definitions for mayonnaise that I've seen before include "Salad dressing" , "Creamy dressing" , "Egg/oil sauce" , "which is saucy" , "7 for salad" .)
