Canning Salt Buying Guide

What is canning salt and why does purity matter?

Canning salt, also called pickling salt, is a pure granulated salt with no additives. Iodized table salt contains potassium iodide, which can make pickles dark and brines cloudy. Anti-caking agents like calcium silicate or yellow prussiate of soda prevent clumping but can also cloud liquids. Dextrose (a sugar) is sometimes added to table salt to stabilize iodine and can ferment in canned goods. Pure salt ensures your preserved foods look and taste as intended.

Grain size: coarse vs. fine

Coarse grains dissolve more slowly but are less likely to cake. Fine grains dissolve instantly and measure more like table salt, making recipe conversion easier. Morton’s medium-coarse is a balance – it dissolves quickly enough for cold brine but doesn’t compact as badly as fine salt. If you use fine canning salt, store it in an airtight container to prevent clumping from humidity.

Kosher salt as a substitute

Kosher salt is also additive-free and can be used in canning, but its flake shape and lower density mean you need to adjust the volume. Diamond Crystal kosher salt is about half as dense by volume as fine canning salt, so use 1.5 to 2 times the volume. Morton’s kosher salt is denser, closer to a 1:1 substitution. For best results, stick with a product labeled ‘canning salt’ to avoid guesswork.

Safety Notes

  • Always use canning salt in tested recipes to ensure proper brine concentration for food safety.
  • Do not reduce salt in canning recipes; it’s necessary for preservation and flavor.
  • Store salt in a tightly sealed container in a cool, dry place to prevent clumping.
  • If salt clumps, break it up with a fork or pulse in a clean coffee grinder before using.

What to Avoid

  • Iodized table salt: causes discoloration and cloudiness.
  • Sea salt: may contain minerals or trace elements that affect flavor and clarity.
  • Himalayan pink salt: high mineral content can turn brine pink and alter taste.
  • Salt with anti-caking agents: these additives can make pickles soft and brine cloudy.

FAQ

Can I use kosher salt instead of canning salt?

Yes, but adjust the volume because kosher salt is less dense. Diamond Crystal kosher salt needs about 1.5 to 2 times the volume of canning salt. Morton’s kosher salt is closer to a 1:1 swap.

Does canning salt expire?

Salt does not expire, but it can absorb moisture and clump. Store in an airtight container to keep it free-flowing indefinitely.

Why does my pickle brine turn cloudy?

Cloudy brine is often caused by using table salt with anti-caking agents or iodine. It can also result from hard water minerals or over-fermentation. Use pure canning salt and filtered water for clear brine.

Final Verdict

The Morton Canning and Pickling Salt is the top choice for home canners who want clear brines and crisp pickles, with Ball Canning Salt as a fine-grind alternative and Diamond Crystal Kosher Salt as a budget option if you adjust measurements.
