With warabi mochiko or warabi starch, I was able to make a delicious tofu without using kidzu.

If you like sesame, you can add more of it. It's also good to use ground toasted sesame seeds. I used the type of warabi mochiko for making desserts. It doesn't make much difference whether you add the pinch of sugar or not, but I added it hoping that it would become firmer. Recipe by commeline
