How to reheat sweet and sour chicken in a saucepan

If you do not have a microwave or oven, you can reheat both the gravy and chicken separately in a saucepan and then plate them together.
What to do so that your sweet and sour chicken remains crispy
Until you are ready to plate your sweet and sour chicken, you should keep the sauce and the chicken pieces separately. This way, the chicken will remain crispy.
In case you already soaked the chicken in sauce, use paper towels to pat the chicken dry. It may not be as crispy as it was before, but it will still be crisp.
Storing the chicken

You should store sweet and sour chicken in an airtight container and refrigerate it.
However, if you want it to last for much longer, you should freeze it. Frozen sweet and sour chicken can last for three months.
It would be best if you stored the chicken and the sauce separately. If the chicken was already in the sauce, remove it and pat dry using paper towels before freezing.

How to properly freeze sweet and sour chicken
To freeze sweet and sour chicken, you first need to let the chicken cool completely. Separate the chicken pieces from the sauce and then use paper towels to dry the chicken pieces.

Pour the sauce into a freezer bag (preferably heavy-duty) and squeeze out all the excess air. In a separate freezer bag or airtight container, place the chicken pieces and seal them tightly.
Place the freezer bags in your freezer. When frozen properly, the sweet and sour chicken will retain its good quality for up to three months.
You may want to remove the bell peppers from your sauce before freezing because they tend to get mushy when frozen.
You can always add fresh bell peppers when reheating for that fresh bite. However, if you don’t mind how the peppers keep when frozen, you can choose to leave them intact.
To defrost sweet and sour chicken, place both the sauce and chicken pieces in your refrigerator overnight.

Sweet and sour chicken shelf life
The shelf life of your sweet and sour chicken greatly depends on how you store it. If you keep it in your refrigerator, the sweet and sour chicken will last for three days. If you freeze it, it will last for approximately three months.
Note that you should not leave sweet and sour chicken at room temperature for more than two hours as it will become unsafe to eat.
How to reheat sweet and sour chicken balls

How to make sweet and sour chicken at home

You can make sweet and sour chicken at home by following these seven simple steps.
Step one: Marinate the chicken.
To marinate your chicken, whisk two eggs in a bowl, add cornstarch, rice wine, baking soda, and sesame oil and then stir in your chicken.
Let the chicken rest at room temperature for 20-30 minutes as you prepare the other ingredients.

To make the sauce, you will need sugar, pineapple juice, red wine vinegar, salt, soy sauce, ketchup, cornstarch, and red pepper flakes.
Whisk the ingredients together in a bowl, and once completely combined, set it aside.

In a bowl, whisk together cornstarch, flour, and your preferred seasonings. Use a slotted spoon to remove the chicken from the marinade and add to the breading.

You can cook your chicken by either deep frying, shallow frying, pan-frying, or baking.
All the cooking methods will give you crispy chicken. However, if you want your chicken to be extra crispy, you should deep fry it.

In a large skillet over medium heat, heat one tablespoon of oil. Add pineapple pieces and onions, stir fry for two minutes, and then add ginger, garlic, and bell peppers.
Stir fry the veggies for two minutes.

Step six: Add the sweet and sour sauce.
Add your sweet and sour sauce to the skillet and simmer until the sauce thickens.
