Use chicken thighs for juicier meat and better texture. Don’t skip coating the chicken with cornstarch to achieve a slightly crispy texture. Adjust the spice level by adding or omitting red chili flakes. The sauce can be made ahead and refrigerated for up to a week. Use a natural pressure release to keep chicken tender. Customize sweetness and tanginess by adjusting brown sugar and rice vinegar. Variations include using tofu for a vegetarian option, adding vegetables after pressure cooking, serving over different bases, and making it gluten-free by substituting soy and hoisin sauces.
