Soak in the water for about ten minutes, remove the blood and debris, and then clean.
Add onions, ginger, garlic, and salt. Marinate for half an hour, taste.
Heat the oil to 70% heat, add the onion ginger and stir fry, then add the chicken legs. Stir fry until golden brown on both sides, add a little water (pour your marinated water) for a minute, boil, then pour in cola, simmer on low heat, and finally simmer on the fire.
Let's put some soy sauce before the cola, because the chicken legs are hard to taste.
