One of our favorite dishes at Tako Grill is grilled "Hamachi" collar and whenever it is available we order it. We have found frozen Hamachi collar at the near-by Japanese grocery store but it happened only once. When we got frozen tuna and kampachi sashimi for "Fish for Sushi", they also had "Kampachi" collars カンパチのかま so we ordered them along with the sashimi fish.
Since it has been bitterly cold in Washington, DC, grilling these small items on a charcoal grill outside in the evening was out of the question. Not to be deterred, I decided to grill them in our toaster oven (on "broil" mode). Half way through the cooking, it started smoking. “Eau de Fish” started permeating the house. On my wife's advice, I hastily moved the entire toaster oven under the hood vent for the stove and turned the vent on high. The smoke cleared and I managed to finish the cooking (see below). Next time, I will move the toaster oven under the hood from the start. (Born of necessity we actually found a method to cook other “smelly” items in the toaster oven such as roasted Brussels sprouts which taste good but leave the house smelling of sprouts for days.) I served this with grated daikon and wedges of lemon. It is not as oily as Hamachi but almost equally good. Since it is smaller than Hamachi collar, I served one each.
One package contained three collars (see below). I thawed them slowly in the refrigerator (for 2 days). I salted them and started cooking them on the meat side using the toaster oven on broil after 7 minutes I turned them over so it was skin side up. That’s when it started smoking. After moving the toaster oven under the hood, I continued broiling for another 7 minutes until the skin was crisp and brown and the meat was done.
Japanese kitchen stoves usually have a "fish grill" which appears to do a better job than my toaster oven. But we will be prepared next time, the toaster over will go under the hood the minute I even think of broiling fish.
