Right on. Mirin is yummy stuff. I lived on that over rice with nori for the first week after my big reaction.
Looking in to the rice noodles will report more after some more sleuthing but wanted to FYI on some YMY nori *products*. I would consider YMY, almost any nori really, relatively super safe--BUT
nori wrapped rice crackers, not at all. For nut or shellfish allergies I would stay away from any brand of rice cracker even though whole sheets of packages nori should be fine. The #1 place to find peanuts in Japanese food is snacks, bagged in rice cracker mixes or pressed into larger rice crackers. So even if you see YMY brand nori-wrapped rice crackers my alarms go off for serious cross-contamination risk.
Jessica, I would put the YMY nori sheets in sealed package as very low risk for TNA. I don't remember who has to look out for sesame but sesame would be a concern. Probably lesser for straight up nori but there's smaller sheets of snacking nori (you eat like potato chips) those can often be seasoned with sesame. How shared that equipment might be I honestly don't know.
I'm always jazzed when we add something back to our menu. I made some malay style chicken curry last week. Very top 8 friendly.
