Kumala's edges crisp and caramelize in hot oil, while the inside becomes creamy and sweet with the natural sugars of the potato. The Fijian word kumala refers specifically to their local sweet potato variety, which differs slightly from others grown worldwide. The warm spices—turmeric, cumin, and coriander—create an earthy, slightly peppery contrast that prevents the dish from becoming one-note. This simplicity makes it perfect street food, eaten by hand with nothing but a sprinkle of cilantro and a pinch of sea salt.
Peel and cut the kumala into chunks.
Heat the vegetable oil in a large skillet over medium heat.
Add the kumala chunks and cook, stirring occasionally, until they start to brown, about 10 minutes.
Stir in the ground cumin, ground coriander, turmeric powder, and paprika. Cook for another 5 minutes, or until the kumala is tender and coated with the spices.
Season with salt and black pepper to taste.
Garnish with chopped fresh cilantro before serving.
Peel before cutting into chunks. This gives you better control over the size and ensures even cooking. The peeled surface also browns more evenly in the hot oil.
This usually means the heat is too low or the pieces are too small. Use medium heat and cut chunks about 1 inch each. Let them sit undisturbed for a minute or two to develop a crust before stirring.
A tamarind-based dip, coconut chutney, or even simple lime-salt mixture work beautifully. The natural sweetness of kumala needs acidic or salty accompaniments to shine.
Reheating will make it soft rather than crispy. It's best eaten fresh from the pan. However, room-temperature kumala is still delicious and works well for packed meals or picnics.
You can bake kumala in a 425F oven for about 30-35 minutes, tossing halfway through with oil and spices. It won't brown quite as much, but it's still delicious and less oily.
