Sour Salt, also known as citric acid is a natural ingredient found in all citrus fruits. You can buy it on some spice racks or online. It looks like small white crystals and has many uses in cooking, canning and flavoring and cleaning. Citric acid is a naturally occurring weak acid that is safe for human consumption and use.
Mixed with water into syrup, sour salt can be used during the preserving process or added directly to the can or jar; methods vary depending on what you are preserving. Citric acid is added to a variety of foods to help prevent various types of food poisoning including botulism. When added to fruits or vegetables with low acidic levels, citric acid will also minimize discoloration in order to avoid a brownish appearance. It's especially useful as a natural food preservative.
Citric acid is popular for sour flavoring or simply to balance the taste of sweet and sour. Some people use it when making traditional stuffed cabbage to get that sweet and sour taste or in cabbage soup.
