Take a rich chicken bone stock and toss in a handful of whole ground spices and herbs. Add a whole chicken leg, braised until the meat is almost sliding off the bone. Slip in a bouquet of cooked vegetables – the bare minimum being carrot, broccoli, bell peppers, eggplant and potato – and serve alongside rice. This is a classic Hokkaido soup curry, a spicy, vibrant soup-and-rice dish guaranteed to warm even the cold, dead bodies of your enemies. But this isn’t its final form. Like the Choose Your Own Adventure books of the 1980s, you can customize almost every aspect of your bowl.
