You won't be able to tell at all that these dango have tofu in them. The sauce is light on the sugar, too, so it's a relatively healthy dessert.
The mitarashi dango they sell in stores are just too sweet for my taste. This recipe keeps the sugar to a minimum, and has tofu for an extra bonus.
The sauce tends to stiffen too much if you overcook it. Try to move the pot of sauce away from the heat when you think it's just started to thicken a little.
Enjoy Japanese food around the world.
