The saury will be filleted
Mince the saury using a knife(be sure to gut and remove the bones).
Those who want to avoid bones can put the fish into a mixer.
In a bowl, mix together the minced saury, tofu, potato starch, and miso.
If the mixture does not hold well, add potato starch until it does.
Once you have a mixture that holds up well, ball up the mixture into two even size patties, then begin frying in a pan with oil.
Once both sides of the burgers have browned, cover the frying pan with a lid, lower the heat, and allow the burgers to steam.
In the meanwhile, grate the daikon radish.
Once the burgers are cooked all the way through, move them to serving plates and add the grated daikon radish, ponzu sauce, and scallions to taste.
