Why does frozen food cook well in an air fryer?

Ice crystals on frozen food turn to steam under heat, keeping the interior moist while the air fryer's rapid circulation strips that steam away fast, crisping the exterior before it goes soggy. Cooking time is only 3–5 minutes longer than fresh — no thawing needed.

What is the Maillard reaction?

The Maillard reaction is a chemical reaction between amino acids and sugars that occurs at temperatures above 140°C (280°F). It creates the brown color, complex flavors, and aromas you associate with seared meat, toasted bread, and roasted vegetables. It's not caramelization — that's sugar-only.
