Not All Salts are Created Equal for Canning
The salt you shake on your dinner is not the salt you should be putting in your canning jars. Standard table salt is packed with additives like iodine and anti-caking agents (such as yellow prussiate of soda or calcium silicate). These extras are great for keeping salt free-flowing in a shaker, but they are disastrous for preserving.
Those anti-caking agents don’t dissolve fully in a brine. The result is a cloudy, murky liquid that looks unappetizing and can leave a layer of sediment at the bottom of your jars. More importantly, the iodine in iodized salt can darken your pickles and vegetables, turning them an unappealing grayish-brown. It can also impart a subtle but distinct metallic or bitter flavor that has no place in your preserves.
For successful canning, you need a pure salt. This means a salt composed of just sodium chloride, with nothing else added. This ensures your brines stay crystal clear, your vegetables retain their bright, natural color, and the flavor is clean, enhancing the taste of your harvest rather than interfering with it.
Morton Canning & Pickling Salt: The Gold Standard
When you walk into almost any store during canning season, this is the blue box you’ll see. Morton Canning & Pickling Salt is the workhorse of the preserving world for a reason. It’s pure, granulated sodium chloride with zero additives.
This salt is designed specifically for canning. Its fine grains dissolve quickly and completely in both hot and cold water, which is crucial for creating a consistent brine. There are no anti-caking agents to cloud your jars and no iodine to discolor your beautiful green beans or crisp cucumbers. It’s reliable, widely available, and affordable.
If you are following a tested recipe from a trusted source, it was likely developed using a salt just like this. Its density and composition are the standard, so measuring by volume (like tablespoons or cups) will give you the safe, expected results. For anyone just starting out or who values consistency above all else, Morton is the safest bet.
Ball Canning & Pickling Salt for Clear Brines
Ball is another name synonymous with canning, and their pickling salt is formulated with the same high standards as Morton’s. It is a pure, fine-grained salt containing no iodine or anti-caking agents. Its primary purpose is to ensure the quality and safety of your home-canned goods without interfering with flavor, color, or clarity.
Where some see a slight difference is in the ultra-fine texture of Ball salt. It seems to dissolve almost instantly, which is a small but welcome benefit when you’re making large batches of brine. This rapid dissolving helps guarantee that every jar has a perfectly balanced salinity, which is critical for both preservation and taste.
Think of Ball and Morton as two sides of the same coin. They are interchangeable in recipes and deliver identical, high-quality results. Your choice between them will likely come down to local availability or brand loyalty, but you can rest assured that either one will produce clear, flavorful, and beautifully preserved vegetables.
Diamond Crystal Kosher Salt: A Canner’s Secret
Here’s a tip you won’t find in most mainstream canning books. While most kosher salts contain anti-caking agents, Diamond Crystal brand does not. This makes it a fantastic, pure alternative if you can’t find dedicated canning salt. But there is a crucial catch.
Diamond Crystal Kosher Salt is made of hollow, flaked crystals, unlike the dense cubes of canning salt. This means it is much less dense. A cup of Diamond Crystal weighs significantly less than a cup of canning salt. You absolutely cannot substitute it 1:1 by volume in a recipe. Doing so will result in a brine that is not salty enough, which is unsafe for preservation.
To use it safely, you must convert your recipe to use weight instead of volume. For example, if a recipe calls for 1 cup of canning salt, you would use the equivalent weight (around 250-280 grams, depending on the brand) of Diamond Crystal. It’s an extra step, but its purity and clean flavor make it a go-to backup for many seasoned canners.
Mrs. Wages Salt for Crisp, Flavorful Pickles
Mrs. Wages is a brand deeply rooted in the pickling tradition. While they sell a variety of mixes, their pure Canning & Pickling Salt is formulated for the pickling perfectionist. It’s another high-purity, additive-free salt designed to dissolve cleanly and deliver a pure, salty flavor.
This salt is often found alongside other Mrs. Wages products like Pickle Mix or Xtra Crunch granules (calcium chloride). This association has cemented its reputation as the salt for people who are serious about crispness. While the salt itself is what prevents spoilage, using it as part of the Mrs. Wages system is a popular way to achieve that signature crunch.
Fundamentally, Mrs. Wages salt is functionally identical to Morton and Ball. It’s a fine-grained, pure sodium chloride that will give you excellent results. If you’re already buying other Mrs. Wages supplies, it’s a convenient and trustworthy choice to complete your pickling toolkit.
Redmond Real Salt for Mineral-Rich Preserving
Now we move into the unrefined salts. Redmond Real Salt is harvested from an ancient seabed in Utah and is prized for its rich profile of trace minerals. Unlike the pure white salts, it has a natural pinkish hue and a more complex, slightly sweet flavor.
Using an unrefined salt like Redmond is a deliberate choice with clear tradeoffs. The primary benefit is nutritional; you’re re-introducing trace minerals that are stripped from refined salts. Many people feel this also adds a superior, more nuanced flavor to their preserved goods.
The downside is appearance. Those same minerals that add nutrition can cause your brine to become slightly cloudy or hazy. They can also cause very light-colored vegetables, like cauliflower or onions, to take on a faint pink or tan tint over time. If pristine clarity is your goal, stick with traditional canning salt. If you prioritize mineral content and complex flavor, Redmond is an outstanding choice.
Fine Ground Celtic Sea Salt for Natural Canning
Harvested from the coastal regions of France, Celtic Sea Salt is another popular unrefined option. It’s known for being moisture-rich and retaining a full spectrum of minerals from the ocean water it came from. For canning, it’s essential to choose the fine ground variety.
Coarse sea salts dissolve too slowly and unevenly in a brine, creating pockets of varying salinity that can compromise safety and texture. Fine ground Celtic salt, however, dissolves much more readily, making it suitable for pickling brines. Like Redmond, it offers a more robust flavor profile than refined salt.
The tradeoffs are also similar. The high mineral content, particularly magnesium, can lead to a slightly gray or cloudy brine. The flavor is distinctly briny and can be more pronounced than other salts. This is a salt for the canner who is committed to using natural, minimally processed ingredients and accepts the cosmetic imperfections that may come with them.
Fine Himalayan Pink Salt: A Modern Homestead Pick
Himalayan Pink Salt has become incredibly popular in modern homesteading circles, valued for both its mineral content and its beautiful color. Harvested from ancient salt mines in Pakistan, its pink hue comes from trace minerals like iron oxide.
Just like with other unrefined salts, you must use a fine-ground version that is certified pure and free of anti-caking agents. The same rules apply: the minerals will add flavor and nutritional value, but they will almost certainly make your brine cloudy. The pink color will not dye your vegetables red, but it can impart a subtle off-white or brownish tint to them over time.
Choosing Himalayan salt is a statement. It aligns with a modern approach to whole-foods preservation, where nutrient density is often valued over the visual perfection sought by previous generations. It works beautifully, but you have to be willing to trade that crystal-clear brine for a jar full of mineral-rich goodness.
Ultimately, the best salt is the one that matches your goals. Whether you prioritize the visual perfection of a crystal-clear brine or the nutritional complexity of an unrefined mineral salt, choosing a pure, additive-free option is the first and most critical step to a safe and delicious pantry.
