This recipe appealed to me because the ingredients were simple and there was no fieriness in it to be found. One thing I substituted out was the mirin for saké. I don't have mirin on hand but I always have saké around because lots of Kylie Kwong's recipes call for it.
I have to say, this was a bit on the flavourless side. I let it marinate for an hour, but it seemed like little of the marinade stuck to the beef to flavour it. In theory, this should have been tasty. Was it the saké substitute? Would the mirin have packed more punch? I don't know. But, next time I might try saving the marinade and thickening it with cornstarch to retain some flavour.
I accompanied the dish with Kylie's Bok Choy with Oyster Sauce.
