Cook Rombauer (4)
I believe the answer is:
irma
'cook rombauer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for irma that I've seen before include "The girl for Irish music award" , "Lady" , "Girl's name ("La Douce")" , "woman" , "- la Douce (1963 film)" .)
