I love Chinese sour cabbage so much, but it is not always easy to find it from supermarkets. sometimes when I am lucky to find one they don’t taste quit right to me. So I started searching online for recipes. This one is easy and the result is so good. Only 3 basic ingredients: cabbage, cold water, and salt.
Quarter the cabbage, if it is dirty outside then clean it with running water. Add 2% salt (2% the weight of the vegetable), sprinkle over the cabbage. Let it marinate for 1-2 hours, water will come out of the cabbage so the vegetable will become soft.
Use a glass container with lid ( I don’t have one, so I used a big china mixing bowl), add the cabbage to the glass container or bowl, make sure add the water from the vegetable back to the container too.
If the water is not covering the cabbage, then add more water to it. Make sure add 2% of salt again to the water(2% the weight of the water). Get a big stone to press down the vegetable and leave it on top of the vegetable to make sure the vegetable is totally under the water ( again I don’t have a stone at home either, so I use a clear plastic bag to hold enough water in it to substitute it). Seal the container with the lid and leave it for 2-3 weeks in room temperature( I seal mine with plastic wrap). Depend on the temperature, the time will vary, I did it for 2 weeks and it was sour enough for me.
When it is sour enough for you, take it out of the water and squeeze the excess sour juice then put it in a zip lock bag and freeze it.
