Step 1: Cook & Season the Sushi Rice (Rinse until clear, cook, then fold vinegar, sugar, and salt while hot).
Step 2: Mix the Spicy Tuna Filling (Combine chopped tuna, spicy mayo, and sriracha, then chill).
Step 3: Prepare Rolling Station (Wrap bamboo mat in plastic wrap and place nori rough-side up).
Step 4: Spread the Rice Layer (Press rice evenly, leaving a 1/2-inch border at the top edge).
Step 5: Layer Core Ingredients (Place spicy tuna, cream cheese strips, and jalapeno matchsticks).
Step 6: Roll and Secure (Fold mat over fillings, tuck tightly, and roll to seal).
Step 7: Slice with Precision (Use an ultra-sharp wet knife to cut into 8 uniform pieces).
Step 8: Optional Oven-Baked Finish (Bake at 375°F for 10-12 minutes with extra spicy mayo drizzle).
