Otherwise, sushi is delicious though I have a hard time rolling it. I have a bamboo mat & I line it with plastic wrap before I place the sushi rice in it. Still, the sushi roll is rather ugly, but it does taste good.
Just sounds like the same thing as makkoli or dong-dong-ju of Korea. It had been the most popular wine in Korea. It is notorious for the headache you get after drinking a lot of it.(this is partly because Koreans drink like crazy) – Any kind of unfiltered wine containes a relatively higher proprtion of methanol. And this turns into the worse kind of aldehyde(form-aldehyde, a toxical material if I remember it correctly) that gives you headache. In the filtered(distilled) wines, including Sake, contains less amount of methanol, easier to evaporate, thus gives less headache.
By the way, try warm sake in the cold winter night next time. (yummy)
