No, three catties of sea eel can't be kept for more than two and a half hours. If stewed for too long, meat will rot easily, which will destroy amino acids in food, increase purine content and lose a lot of nutrients. Stewing method of sea eel:

1. Wash the sea eel, wash the internal organs, and wash the shredded ginger and chives properly for later use.

2. Put oil in the pot and stir fry the small ingredients. Add the sea eel cooking wine and stir-fry for about two minutes. Add a small glass of water and simmer for 15 minutes with salt.
