In a small bowl, whisk together the mayonnaise, Thai sweet chili sauce, sriracha sauce, honey, and lime juice until well combined. Set aside.: Right away you ll notice the sauce come together with a glossy sheen and a sweet spicy aroma, a blend of tangy citrus and warm chili that makes your kitchen smell inviting. Vigorously whisking emulsifies the mixture so it coats the salmon instead of sliding off, and the texture should be smooth and slightly thick. Taste and adjust the heat with more sriracha if you want sharper notes, or a bit more honey if the sauce feels too sharp. A common mistake is under mixing which leaves pockets of unmixed mayonnaise , making the sauce uneven; take an extra 15 seconds to ensure a uniform, glossy sauce.
In a large bowl, combine the salmon bites, olive oil, garlic powder, onion powder, smoked paprika, salt, black pepper, and cayenne pepper. Toss until the salmon bites are evenly coated with the seasonings.: When you toss the seasoned salmon you should see a thin, even film of olive oil and spices clinging to each piece, the paprika lending a warm reddish hue. The scent of garlic and smoked paprika will rise, hinting at the savory profile to come. Even coating is crucial so each bite crisps equally; if pieces stick together break them apart gently. A typical mistake is overcrowding the bowl and not coating evenly, which can leave bland spots in the final dish.
Preheat your air fryer to 400°F (200°C) for about 3 minutes.: As the air fryer reaches temperature you may hear a faint hum and feel a gentle heat if you open the drawer briefly, and the preheat ensures rapid searing on contact so the exterior crisps quickly. Preheating prevents the salmon from slowly warming and steaming, which would ruin crispness. If you skip preheating, the bites can end up pallid and soft instead of golden edged; take the short time to preheat for the best texture.
Place the salmon bites in the air fryer basket in a single layer, making sure they are not overcrowded. You may need to cook them in batches. Air fry the salmon bites for 8-10 minutes, shaking the basket halfway through, until the salmon is cooked through and crispy on the edges.: You want to hear a light sizzle as hot air circulates, and visually the pieces will turn from glossy raw pink to an opaque, flaky finish with slightly caramelized edges. Shaking the basket halfway helps each piece develop even browning and prevents steaming. Resist the urge to pile them in; overcrowding traps moisture and prevents crisping, resulting in soggy bites. If in doubt, cook in two quick batches to preserve texture.
Transfer the cooked salmon bites to a serving platter and drizzle with the Bang Bang sauce. Serve the remaining sauce on the side for dipping.: Once plated, the aroma will be a blend of warm spices and sweet chili, and the contrast between the crunchy edges and the silky sauce is immediately apparent. Drizzling just before serving maintains the crispness, while extra sauce on the side lets guests control sauciness. A common error is saucing too early which softens the crust; wait until just before you serve to keep that satisfying crunch.
