Whether you’re looking to preserve summer’s bountiful harvest or prepare some crispy, tangy pickles, understanding the differences between pickling salt and canning salt is key. Though they may sound similar, these specialty salts vary in some important ways that impact their effectiveness in recipes for pickled and canned goods. Using the right type of salt for your specific purpose allows you to achieve the desired flavors, textures, and fermentation while also ensuring safety. This article will unpack the purpose and properties behind canning versus pickling salt, explain when and why you’d use one over the other, and provide best practices for leveraging their unique benefits. With some helpful insights into the proper usage of these salts, you’ll feel confident that your pickled creations and canned produce will maintain quality and taste great all year.

Key Differences Between Pickling Salt and Canning Salt

Purpose and Uses

Encouraging Fermentation

The purpose of pickling salt is to encourage fermentation while preserving foods. It contains no added iodine or anti-caking agents, allowing the lactic acid bacteria responsible for fermenting pickled vegetables like cucumbers to thrive. The fine, uniform grains also dissolve easily to create a saline brine.

Preserving Produce

Meanwhile, canning salt serves a different function: safely preserving foods using heat processing. Due to its more varied crystal size, canning salt helps maintain firm texture and balanced flavors in canned produce without over-softening delicate fruits and vegetables during the heating process. It allows just enough heat penetration to kill harmful microorganisms while retaining the food’s shape.

Pickling vs. Canning Candidates

While softer produce like peaches, pears, and tomatoes are best suited for canning with canning salt, firmer fruits and veggies with less moisture like cucumbers, cabbage, onions, and peppers tend to be better candidates for pickling with pickling salt. Their crunch stands up well to fermenting brines.

Pickling Salt

Definitions and Properties

Pickling salt, also known as canning and pickling salt or preserving salt, is a specialty salt made specifically for fermenting and pickling foods. Unlike table salt, it contains no iodine or anti-caking additives. Pickling salt has fine, uniform crystals that easily dissolve to create brines ideal for the pickling process. Its purity allows for a proper fermentation environment without interfering.

The lack of additives also enables salt to fully permeate foods. This is vital to inhibiting the growth of dangerous microbes that can cause spoilage or illness.

Uses in Pickling

Pickling salt is the preferred choice when making preserved items like pickled vegetables, fruits, eggs, and meats. Uniform crystals allow it to permeate the food’s skin and tissue thoroughly as it draws moisture out. This crisping effect preserves the food’s fresh crunch even when soaked in brine for extended periods, creating the characteristic texture we expect from pickles and relish.

Meanwhile, the salty brine established by fully dissolved pickling salt lowers the overall pH. This boosts populations of beneficial probiotic lactobacilli while suppressing harmful bacteria. An environment with the proper acidity and salt concentration thus kickstarts and sustains the fermentation pickle creators rely on.

In addition, pure pickling salt contains no problematic heavy minerals. Impurities like magnesium and calcium found in table salt can cause cloudiness and other off flavors. Pickling salt’s purity keeps brines crystal clear. Its neutral taste also provides the ideal backdrop for spices, herbs, garlic, and other seasonings to shine rather than adding competing notes.

Canning Salt

Definitions and Properties

Canning and pickling salt is another type of preserving salt designed for home canning and pickle making. However, unlike pickling salt, canning salt features larger, irregular crystals with more impurities and mineral content. This unique composition serves an important purpose.

Uses in Canning

During a water bath or pressure canning, the salt helps retain the shape and firm texture of delicate fruits and vegetables. The minerals like calcium and magnesium aid in heat transfer, while the mixed crystal sizes distribute it evenly. This prevents over-softening produce as jars achieve the temperature needed to kill dangerous bacteria.

Additionally, the residual mineral taste balances flavors. This allows the fresh flavors of the food itself to pop, rather than being overpowered by salty brine. Canning salt provides just enough salinity and seasoning to offset bitterness or acidity when preserving fruits, tomatoes, pickles, salsa, and more.

Using non-iodized canning salt eliminates the risk of discoloration or strange flavors that table salt additives can cause. It helps create a clean-tasting, properly balanced end product. Following established guidelines for the correct proportions of canning salt ensures your canned jams, vegetables, and salsas achieve the right texture and taste every time.

Best Practices

When to Use Each Type

Knowing when pickling salt is preferable to canning salt comes down to the preservation method. Pickling salt should be used when fermenting foods like cucumbers, carrots, onions, eggs, and more in a brine. Canning salt is ideal for water baths or pressure canning fruits, tomatoes, and vegetables to be shelf-stable.

While fruit- and vegetable-based goods can be preserved either way, the desired outcome helps determine which salt works better. If aiming for pickled items with crisp texture and tangy flavor, use pickling salt. If wanting softer, fully-cooked canned produce with balanced flavor, reach for canning salt.

Substitution Considerations

In a pinch, canning salt can be used for fermenting pickles instead of pickling salt with minimal issues. However, substituting table salt or pickling salt in canning increases food safety risks and affects texture. Only swap salts when recipes specify that it is safe to account for differences in mineral content.

Proper Amounts Matter

Carefully measure either salt when pickling or canning. Too much salt hinders fermentation, while too little allows harmful pathogen growth. Follow validated recipe guidelines for concentrations suited to each food and preservation method. This ensures quality and safety.

Quality and Safety Assurance

Adhering to other best practices like sterilizing equipment, waiting sufficient time for food to seal or ferment, processing or storing at the correct temperature, and checking for signs of spoilage also guarantees your efforts pay off with tasty, shelf-stable foods your family can enjoy all year.
