There are some dishes in Japan that look and have a texture like tofu, but are not tofu in the traditional sense; that is, they’re not made from coagulated soy milk . One of these not-tofu tofus is _goma dofu_ （ごま豆腐）or sesame tofu. Goma dofu is made from three simple ingredients: ground sesame paste, water, and kuzu or kudzu powder.
Shoujin ryouri (shojin ryori) is the mostly-vegan cuisine that was developed in Buddhist monasteries in Japan, and goma dofu is one of the best known shoujin ryouri dishes. Making it from scratch is hard; kuzu powder is difficult to process from kuzu roots, and the sesame has to be ground for a very, very long time in order for it to become totally smooth. The job of grinding the sesame was assigned to low-level novice monks - the hard work was considered to be good for their character.
But for cooking at home you take two critical shortcuts which make goma dofu a very easy recipe: use readymade kuzu powder, and pre-ground sesame paste. In Japan pre-ground sesame paste is sold as nerigoma, but elsewhere it’s tahini is more readily available. Granted, grinding up your own freshly toasted sesame seeds does result in a slightly more fragrant _goma dofu_, but tahini based goma dofu is still very good.
An easy to make version of the shoujin ryouri or Zen Buddhist temple cuisine classic, goma dofu is a tofu-like dish made with ground sesame paste and kuzu (kudzu) flour. It’s delicious chilled and served with a little wasabi and soy sauce.

Use hulled white sesame seeds, toast lightly in a dry pan, and grind for about an hour or so in a suribachi  for about an hour until totally smoooooooth. Character improving, indeed. Strain through a fine sieve before using.
Trivia: the term goma o suru (grind sesame seeds) is a Japanese euphemism for sucking up to (or brownnosing) someone!
Use smooth unsweetened (and preferably unsalted) peanut butter in place of the sesame paste for a peanut tofu.
If you have a gluten intolerence problem, chances are you have already encountered kuzu or kudzu root powder as a gluten-free thickening agent. It’s the starch produced by processing the roots of the kuzu (or kudzu) plant. Here’s what it looks like:
Kuzu is a very good thickener when the dish needs to have a sort of starchy-gelatinous texture and be translucent. It’s used in a variety of savory and sweet dishes in Japan. You can buy it at Japanese grocery stores or health food stores. I find that it’s usually a bit cheaper at Japanese food stores than at health food stores, but it’s still rather expensive since producing it from kuzu roots is a very laborious process.
