The tasty high-acid menu includes choices ranging from sweet to savory. Fruits, fruit juices, jams, jellies and other fruit spreads, salsas, most tomatoes, pickles, relishes, chutneys, sauces, vinegars and condiments are among items safely preserved using the water bath canning method. Because these common foods contain high amounts of acid or the recipe incorporates the correct balance of acid, water bath canning is the recommended method.
