Notes on Quality

Possible Substitutions

Step-by-Step Instructions
Prep: Spicy Tuna Filling
- Finely dice or chop the sushi-grade tuna
- In a bowl, mix the diced tuna with masago, Sriracha, and Kewpie mayo. Let it sit for 10 minutes to enhance flavors. Optionally, add 1 Tbsp rice vinegar and chopped scallions for extra zing
- Thinly slice the cucumber and avocado

Rolling: Using a Sushi Mold
- Place the mold’s cutting guide over its base to form a rectangular shaping box
- Lay a sheet of nori inside the mold with the rough side facing up. Gently press it down
- Spread a layer of seasoned sushi rice (about 1/3 of the mold’s depth) evenly with a spatula or fingers
- Add the spicy tuna filling, then layer cucumber and avocado slices on top
- Cover with more sushi rice, filling the mold completely
- Dab the nori edges with a rice vinegar-water mixture (1:1 ratio) to seal
- Place the heart-shaped lid on top and press evenly to mold the roll
- Carefully remove the lid and use a sharp knife to cut following the cutting guide
- Replace the top lid and press lightly to ensure the roll stays intact while cutting
- Flip the mold upside down, gently tap to release the sushi pieces
- Arrange on a serving plate and drizzle with optional unagi sauce
Expert Tips & Tricks
Best Practices
- Wet your hands to prevent rice from sticking to your fingers while handling
- Use a sharp, wet knife to cut clean slices without tearing the roll
- Apply even pressure when pressing the mold for consistent rolls
Common Mistakes
- Avoid overfilling the roll to prevent breakage
- If the nori is too dry, it may crack; keep it slightly moist with the rice vinegar mixture

Time-Saving Tips
- Make the filling ahead and refrigerate for convenience
- Keep sliced avocado and cucumber ready in the fridge for quick assembly

Presentation Ideas
