Part of an opening line? (6)

I believe the answer is:

sesame

(Other definitions for sesame that I've seen before include "Open ...... is magic phrase for obtaining access" , "Plant cultivated for seeds providing oil" , "Oil-rich seed plant" , "Open .... is a pantomime cry" , "Plant with edible seeds" .)

I've seen this clue in the LA Times.
