One super mega traditional Japanese food offering is wagashi (和菓子), and if you do a search, you'll find hordes of it's-too-pretty-to-eat mounds shaped into flowers and bird nests and artful masterpieces.
We found these at the Tsukiji Fish Market:
Cookpad, you'll see a lot of the home cook'n variety are basically plain old red bean wagashi or a sweet potato variety that look a little less impressive, but still have that old Japan taste.
I grabbed the first recipe I saw and went to work.
150 grams of dried beans
Buncha sugar, but not in an American way
little bit of salt
agar agar - 4 grams isn't much
And then, and then...okay let's try Google translate...
Add in the pot, and boom!
And I was so glad to be done...
