Cut cauliflower into bite sized pieces, then boil or steam for 10 minutes.
Using a suribachi or Japanese grinding bowl, i.e. mortar and wooden pestle, ground the roasted sesame seeds until the seeds are a rough powder.
In a separate bowl, mix together shoyu, mirin, and sugar. I recommend adding a little sugar at a time. I don't like gomaae when it is too sweet and only added a little over ½ tablespoon. Add the seasoning mixture to the suribachi and mix with the ground sesame seeds.
In a large bowl, toss steamed cauliflower and gomaae dressing and voilĂ ! Cauliflower gomaae!
