Kuwai no nimono (simmered arrowhead)
Kuwai, the arrowhead tuber with its proud little sprout, appears in osechi boxes in Kansai and across Japan because it says 'me ga deru': a bud comes out, a wish for success and for children to grow and thrive. It tastes like a cross between chestnut and potato, with a faint pleasant bitterness, and simmering it slowly in sweet dashi gives it a smooth, dense texture. This version is vegan, using kombu dashi, and the seasoning includes mirin, a sweet rice wine (for no alcohol, swap the mirin for 2 tbsp water plus 2 tsp sugar). Serve it at room temperature among the other osechi dishes, or with grilled fish and rice. Chef's tip: leave the tubers to cool completely in their liquid; that is when they soak up the flavour.
