Preparation of ingredients:

2 kg of fresh crab, 4 slices of ginger, 4 onions, 5 peppers, 3 garlic and 2 teaspoons of salt.

Production method:

1. First, brush the hairy parts and abdomen of the crab without removing the cheeks. Pay attention to choosing fresh crabs. Crabs left too long will not only be tender, but also fall off when cooked.

2. Then beat the onion into a onion knot, slice the ginger, and dice the garlic and pepper.

3. Put the crab into the pot and add the cold water that hasn't eaten the crab. Be careful, it must be cold water.

4. Add onion knots, ginger slices, garlic and peppers, cover the pot and turn on a small fire. Be sure to cook slowly. If you don't eat spicy food, you can put a little less pepper.

5. After boiling, skim off the floating foam, add salt, and continue cooking for about 15 minutes.

6. Don't lift the lid immediately after boiling, and then simmer 15 minutes to taste completely.

What's the use of boiling crabs with cold water and small fire?

You can avoid falling off the crab's feet. Because both hot water and fire have overheated temperatures, crabs will increase their struggle strength in the pot, which will lead to excessive force and their feet will fall off. In the process of boiling cold water and small fire, the temperature rises slowly, reducing the crab's struggle.
