A light Dominican soup.
Roast plantains at 400ºF until light golden and slightly crispy. Remove from oven and mash.
Heat the water over medium heat in a large pot. Add the garlic, leek, culantro, allspice, oregano, oil, salt, and pepper, stirring to incorporate. Simmer to develop flavor, adding additional water to maintain the volume as needed.
Add plantain to broth, stirring to mix. Continue simmering until heated through.
Remove allspice berries, adjust salt, and serve topped with cilantro.
Cannot recommend as is. It's very, very bland. I attempted roasting the plantains, but they dehydrated more than they browned, so I then fried them to get some color. I used only cilantro (no culantro), but I don't think that is enough of a change to explain the blandness of this soup.
