You do not need to keep fridge pickles in canning jars. Plastic and glass bowls or containers are perfectly fine for anyone trying out fridge pickling, which does not involve processing, especially if specialized canning jars are not available, accessible, or just too expensive. Indeed, use food-grade plastic bowls from the kitchen, not plastic containers used for outdoors or non-food items. However, do not use aluminum, copper, brass, galvanized, or iron utensils or containers. These will react with the salt and acids during pickling. This can cause undesirable changes to the pickles. Other 1- to 3-gallon non-food-grade plastic containers may be used if lined inside with a clean food-grade plastic bag.
