Pressure Canning Salsa
Earlier, hot water canners were used to can tomatoes, salsa, sauces, etc. However, people have discovered that using a pressure canner results in better quality. It is used in low acidic foods, i.e., food with pH level of above 4.6. For recipes with fresh tomatoes, lemon juice, vinegar, and citric acid are used as preservatives. The following recipe can be made hot with the use of Serano chili pepper.
