How to Make It
In a large, heavy pot, heat the oil. Add the onion, ginger and garlic and cook over moderate heat, stirring occasionally, until softened, 5 to 6 minutes. Add the habanero, cumin and turmeric and cook, stirring, for 2 minutes. Add the squash, season with salt and cook, stirring, until the squash is coated with the seasonings in the pan. Add 3 cups of the broth and bring to a boil. Simmer over moderately low heat, stirring occasionally, until the squash is nearly tender, 5 to 6 minutes. Stir in the okra and cook until tender, about 3 minutes.
In a bowl, whisk the cashew butter with the remaining 1/2 cup of broth. Stir the mixture into the stew and simmer for 5 minutes. Serve the stew in deep bowls, garnished with cilantro.
