This is a subtle, comforting dish, best served still slightly warm. If you are having this as a main course, add some cooked mung beans or other protein of your choice and perhaps a few halved cherry tomatoes for color. If you cannot find black rice noodles (which provide a great color contrast), regular soba or rice noodles will do just fine.
For this recipe, we prefer the steady, even heat of a cast-iron skillet. A heavy stainless-steel skillet may be used, but you may have to increase the heat slightly.
