Bluefin Tuna Belly, known as 'Toro' in Japan, is one of the most sought-after parts of the fish due to its sumptuous and luxurious taste profile. Its beautiful, deep pink to reddish-brown hues are a sign of its exceptional quality and culinary value. This particular cut of bluefin tuna is celebrated for its high-fat content, which gives it a deep, rich flavor, an opulent melt-in-your-mouth texture and a subtle sweet undertone that lingers on the palate. It is often used in high-end sushi and sashimi recipes, but is also amazing to be seared or gently grilled. As Bluefin Tuna is an endangered species, it's crucial to ensure the source is ethical and sustainable when purchasing.

Bluefin Tuna Belly, also known as Toro, is a delicacy and generally not found in a standard grocery store due to its high cost and rarity. You would typically find this at a specialized or high-end seafood market or at sushi restaurants. You may also be able to find it through online gourmet food retailers. Always ensure that it is sustainably sourced.
