1. Stir-fry: Stir-fry bitter melon and chili together to reduce the bitterness.

2. Salting: Sprinkle the cut melon slices with salt and marinate for a while, then filter the water to reduce the bitter taste. Cut the bitter melon into pieces, marinate it with salt for a while, and then stir-fry it to reduce the bitterness and keep the flavor of the bitter melon.

3. Blanch: Cut the bitter melon into pieces, boil it with water first, and then soak it in cold water. Although the bitterness can be removed, the flavor of the bitter melon is lost.

4. Rinse in water: Cut the bitter melon open, remove the seeds, and cut it into strips, then rinse it with cold water, pinch it gently with your hands while washing it, wash it for a while, change the water and wash it again, and rinse it repeatedly. After three or four times, the bitter juice will be lost with the water and the bitter taste will be removed. There is no need to scald it with boiling water or salt it. After being fried in this way, the bitter melon tastes delicious and slightly bitter.
