I'm going to keep playing with it. So far, I've tried asparagus & shrimp. A single recipe covered a pound of each. For the rice flour, you can substitute 7/8 c. flour + 2 T. cornstarch. I think the rice flour might make it taste lighter, though. Only half of both the sugar & oil were needed.
Just made this, it takes a while, about 90m, used a frydaddy, which pobably holds less at a time, so that may be why. Tamari is basically soy sauce, used 12 x-jumbo shrimp,(2 minutes for shrimp)6 spring carrots, and about 3 oz snap peas, halved batter and sauce, which left 2 of us stuffed. Very tasty, will make again, but with frypan to cut time. Side of teryaki noodles.
