Mother Brine of Sichuan Paocai

Orange juice? No! This is called 母水 (mǔ shuǐ) in Chinese, also known as mother brine. Mother brine, to many people’s surprise, is an essential part of Sichuan fermentation if you are to make great paocai. It deepens the flavor with every batch, building layers of acidity, aroma, and complexity that fresh brine alone cannot achieve. Passed between friends, neighbours, and families, it becomes more than technique, it’s a gesture of trust, a living piece of someone else’s kitchen finding its place in yours.
