Variations

• Make sure to use very fresh, high-quality fish for this dish. Such fish is often marked "sushi grade" in the market. Use other fish — halibut, snapper, swordfish — if you like.
• Other possible additions: cubed red peppers, grated carrots, diced red onion, minced garlic.
• Sometimes a pinch of sugar is added to take the edge off the acidity.
