Pickling preserves low-acid vegetables and prevents foodborne illnesses. Tips include using fresh vegetables, appropriate jar sizes, firming agents, and proper canning procedures to avoid botulism.
Pickling is a form of food preservation used to contain low-acid vegetables. Low-acid vegetables should be pickled if they are being prepared in a hot water bath to kill bacteria and prevent foodborne illnesses such as botulism. The best tips for pickling vegetables often depend on the type of vegetable canned and the preferences of the individual. Tips for pickling vegetables include using fresh vegetables, maintaining freshness, and canning and storing vegetables. Brining with accurate amounts of vinegar, pickling spices, garlic, and any other desired spices should be proportioned accurately.
One of the best tips for pickling vegetables is to make sure the jars are the appropriate size for the recipe being used. It is important to use the appropriate jar size to properly and safely marinate vegetables. If a recipe calls for a jar of one size, but a larger size is used, the brine won’t be in proportion to the size of the jars, and there won’t be enough brine to thoroughly cover the vegetables. It is important that they are completely covered with brine.
When pickling vegetables, fresh, freshly picked vegetables should be used in an effort to maintain freshness. Long-lasting vegetables lose pectin and become soft. Once the vegetables have softened, they cannot be crunchy again. The flower ends of vegetables should be cut off, as the flowers contain microbes that can cause mushyness.
Another way to maintain or add to the freshness of fresh vegetables in the pickling process is to add alum, lime, calcium or another firming agent to the brine. When using firming agents, it is important to use the appropriate amounts. Too little or too much can have the opposite effect and soften the vegetables. Soaking vegetables in ice water for a few hours before pickling will help them maintain freshness.
Proper canning procedures must be used to avoid the dangers of botulism. Vegetables should be packed in sterilized jars and completely covered in brine. Headroom should be left at the top of the jar to allow for bubbling and expansion of the vegetables. The amount of headroom required varies depending on the type of vegetable and the recipe. If not enough space is left, the contents of the jars may boil or cause the jars to explode.
