Ingredients

• 300 g White rice ( cooked )
• 4 piece nori seaweed ( whole sheets )
• 150 g Tuna ( drained )
• 2 tbsp Japanese mayo
• 1 piece Persea americana Mill. ( sliced )
• 0.5 piece Cucumber ( thinly sliced )
• 3 tbsp Rice vinegar
• 1 tbsp White sugar
• 1 tsp Gray sea salt
• 300 g Sushi rice (short grain) ( well rinsed in clear water )

Instructions

1. Preparing the rice

   Rinse the rice in clear water until it runs clear. Cook with an equal volume of water. Once cooked, pour the rice vinegar mixed with sugar and salt over the hot rice. Mix gently to avoid breaking the grains.

2. Preparing the filling

   Mix the drained tuna with Japanese mayonnaise until well combined. Slice the cucumber into thin strips and the avocado into regular slices.

3. Assembling the sandwich

   Place a nori sheet on plastic wrap, corner pointing up. Place a square of rice in the center. Layer the tuna, then avocado and cucumber. Cover with a second layer of rice the same size as the first.

4. Folding and tightening

   Fold the four corners of the seaweed toward the center to close the sandwich. Wrap tightly with plastic wrap so the seaweed softens against the rice and seals perfectly. Let rest for 5 minutes.

5. Final slicing

   Remove the wrap. Using a very sharp, wet knife, cut the sandwich in half. The blade should slide through without crushing the rice for a clean cut.

Chef's tips

• Dampen your hands with vinegared water to handle the rice without it sticking to your fingers.
• Run your knife blade under hot water between each cut for a perfect visual result.

Storage

Consume immediately to keep the seaweed crisp. Do not store in the refrigerator as the rice will harden.
