Which ingredient adds a tropical flavor to the Tuna Poke Bowl?

Mango is the ingredient that adds a tropical flavor to the Tuna Poke Bowl. This is due to its sweet and juicy profile, which complements the savory elements of the dish, such as fresh tuna and other vegetables. The inclusion of mango not only enhances the flavor but also adds a vibrant color and a refreshing contrast to the other ingredients, making the dish more visually appealing and flavorful.

While radish, micro cilantro, and green onion each contribute their own unique flavors and textures—such as crunchiness from the radish, a fresh herbaceous note from the micro cilantro, and a mild onion flavor from the green onion—they do not evoke the tropical essence that mango brings. Mango's distinctive sweetness and tropical notes create a harmonious balance that elevates the overall composition of the Tuna Poke Bowl.
