01 - Combine rice vinegar, sugar, and salt in a bowl. Add julienned carrots, sliced cucumber, and sliced radishes. Toss thoroughly to coat and let sit for at least 20 minutes, stirring occasionally to ensure even pickling.
02 - Rinse jasmine rice under cold water until water runs clear. Combine rice, water, and salt in a medium saucepan. Bring to a boil over high heat, cover tightly, reduce heat to low, and simmer for 15 minutes. Remove from heat and let stand, covered, for 5 minutes. Fluff gently with a fork before serving.
03 - Whisk together soy sauce, mirin, honey or maple syrup, rice vinegar, sesame oil, grated ginger, and minced garlic in a small bowl until well combined and honey is fully dissolved.
04 - Place salmon fillets in a shallow dish or sealable plastic bag. Pour half of the marinade over the fish, ensuring fillets are evenly coated. Marinate for at least 10 minutes, up to 30 minutes maximum. Reserve remaining marinade for sauce.
05 - Preheat oven to 400°F. Remove salmon from marinade and place on a foil-lined baking sheet. Bake for 10-12 minutes until salmon is just cooked through and flakes easily with a fork. Alternatively, heat a nonstick skillet over medium heat and cook salmon for 4-5 minutes per side.
06 - Pour reserved marinade into a small saucepan and bring to a simmer over medium heat. If desired, mix cornstarch with 1 tablespoon water and stir into sauce to thicken. Cook for 2-3 minutes until glossy and slightly reduced.
07 - Combine mayonnaise, sriracha, and lime juice in a small bowl. Whisk until smooth and fully incorporated. Adjust sriracha quantity to achieve desired spice level.
08 - Divide cooked rice evenly among four bowls. Arrange salmon (flaked or whole), drained pickled vegetables, sliced avocado, scallions, sesame seeds, cilantro, and nori strips on top. Drizzle generously with prepared teriyaki glaze and sriracha mayo. Serve immediately.
