Tips

Tuna Quality: Only use sushi-grade tuna from a reputable fishmonger. The fish should smell fresh and ocean-like, never fishy.

Avocado Selection: Choose avocados that yield slightly to pressure but aren't overly soft. They should be ripe but still hold their shape.

Serving Temperature: Serve immediately after assembly to maintain the best texture and food safety.

Make-Ahead Prep: Prepare all components separately up to 2 hours ahead, but assemble just before serving.

Presentation Ideas: Use small spoons or chopsticks for elegant serving. Arrange on a platter with ice for food safety.

Substitutions: For a budget option, use high-quality canned tuna. For vegetarian, substitute diced firm tofu or seared tempeh.
