How to Store Sweet and Spicy Mongolian Chicken
Storing left-over sweet and spicy Mongolian chicken is straightforward. Allow the dish to cool to room temperature. You can then place it in an airtight container and store it in the refrigerator. It should last for about 3-4 days.
If you want to keep it longer, consider freezing it. Place the cooled chicken in freezer-safe bags or containers, ensuring you remove as much air as possible. The chicken can last for up to 3 months in the freezer. When you’re ready to eat it, just thaw it in the refrigerator overnight and reheat it in a pan or microwave; it’s just like fresh!
Tips and Mistakes to Avoid
- Don’t skip marinating. Marinating the chicken is crucial for flavor. It allows the soy sauce and cornstarch to penetrate the meat.
- Cut uniform pieces. Remember to cut the chicken and vegetables into similar sizes for even cooking.
- Watch the heat. Be careful with the heat while cooking—too high can burn the sugar while too low may not cook the chicken properly.
- Taste the sauce. Before serving, always taste the sauce. You can adjust sweetness or spice levels to suit your preferences.
Avoiding these common pitfalls can help ensure your sweet and spicy Mongolian chicken turns out delicious every time.
Variation
You can modify this recipe based on your preference. Here are a few ideas:
- Vegetable version: Swap out chicken for tofu or tempeh for a vegetarian option. Just ensure you press tofu to remove excess moisture.
- Different proteins: You can use shrimp or beef instead of chicken to mix things up.
- Add more heat: If you enjoy more spice, consider adding fresh chopped chili peppers or increasing the quantity of red pepper flakes.
