The arare is a Japanese snack of roasted rice crackers seasoned with soy sauce. Furikake is very finely chopped dried seaweed. Of course you know microwave popcorn.
Just pop the corn, pour it out in a bowl, sprinkle on the furikake, and dump the arare on top. For added flavor, shake on some li hing powder. Then mix it all together.
Good to the last kernel!
