Hoisin Sauce … with a side of duck

Mirela arrived back in town late last night, to attend her graduation next Monday, and the first order of today was dinner at my local Chinese for some Hoisin Sauce .. err, I mean Duck with Hoisin sauce. For some reason, and I could see the appeal, Mirela absolutely loves the dark stuff. I quizzed our waitress on the magic formula of the sauce and she said it was a mixture of Hoisin sauce (2/3) and Yellowbean sauce (1/3.) Who would have known.
