Source: 7 Essential Pieces of Canning Equipment
Making jams and pickles involves more than just throwing the contents into a glass jar; if you plan to store the canned item for several months, the cans must be processed using a method of suctioning the seal of the cans to preserve the jar's contents. But before attempting any recipe that calls for canning, it's important that you have all the equipment on hand, especially if you are making jam or pickles for the very first time. Here are the essential items you'll need and the purposes they serve:
- Fine mesh sieve or chinois: If you are making jam and need to strain the fibrous skin and seeds of the cooked fruit, a fine mesh sieve or a chinois is the easiest way strain the juice. The Williams-Sonoma chinois strainer, pestle, and stand ($70) is a jam-making life-changer. Simply place a bowl under the nifty stand, and with the other hand, use the pestle to extract every last drop of cooked fruit juice from the chinois.
