Onsen tamago
In hot-spring towns like Beppu and Kusatsu, ryokan guests find a little bowl beside their breakfast rice: an egg cooked slowly in the spring water, its white barely holding together and its yolk thick like custard, sitting in a splash of seasoned dashi. At home you copy the hot spring with a pan of water held well below the boil. The mistake almost everyone makes is using water that is too hot, which gives an ordinary soft-boiled egg with a set white; keep it at about 70 °C. This version uses a kombu and shiitake dashi, so it stays vegetarian. Because the eggs are only partly set, cook eggs fully for anyone pregnant, young children, older people or anyone with a weakened immune system. Chef's tip: take the eggs out of the fridge 30 minutes early, because a cold egg drops the water temperature and the yolk stays raw.
