I love eating the grilled fish from the fresh fish sheet at Sandbar so it is crazy that the memory that sticks with me from our Mothers' Day dinner was not the perfectly cooked Alderwood-grilled, miso-marinated Sablefish, but the potatoes that I got as a substitute for the regular rice accompaniment. The sablefish was delicious but it was the texture and smoothness of the potatoes that kept me having just one more bite, till - so much for my carb-restricted eating plan - my plate was empty.
