Long cowpea, salt, Kangle vinegar, hot sauce (Hunan hot sauce bought in supermarket), and shallots.

working methods

1. Wash the cowpea (don't pick it at both ends).

2. Pour cold water into the pot and bring to a boil. Add cowpea, cook for about 1-2 minutes, and take out (don't cook cowpea for too long, keep it green).

3. Take the cowpea out of the fish and cut it into cubes with a knife.

This step is very important: put the chopped cowpea into a bowl and add vinegar, salt, hot sauce and chopped green onion while it is hot.
