It is safest to eat steamed crabs

Crab boiling method: wash the crabs, put them in a pot filled with boiling water, add a piece of ginger, and cook them over high heat. Generally, it takes twenty minutes for weights above half a catty and fifteen minutes for weights below six ounces.

Steaming crab method: When the water is boiling, place the crab belly up in a steamer, place washed and dried perilla leaves on top, and steam for fifteen to twenty minutes.

Dipping ingredients: use one and a half bowls of vinegar, three and a half bowls of soy sauce, six spoons of sugar, mince four sections of ginger and simmer in water for twenty minutes.

Be careful when eating steamed crabs. After the water boils, you need to cook them for at least 20 minutes. Only when they are cooked thoroughly can the germs in the crab meat be killed. When eating, you must remove all four substances: crab gills, crab heart, crab stomach, and crab intestines. These four things contain bacteria, viruses, sludge, etc.
