If you’re new to canning or pickling, you may have come across recipes that specifically call for canning salt. But what exactly is it—and do you really need it?
Canning salt is a pure, fine-grained salt that dissolves easily and does not contain additives like iodine or anti-caking agents.
These additives, commonly found in table salt, can cause cloudiness or discoloration in pickled foods.

What Is Canning Salt?
Canning salt is a pure granulated salt made specifically for food preservation.
It contains:
- No iodine
- No anti-caking agents
- No additives
Because of this, it dissolves cleanly and evenly in brines, making it ideal for pickling and canning.
Why Use Canning Salt?
Using the right type of salt matters more than you might think.
Keeps brine clear
Additives in table salt can make your pickling liquid cloudy.
Maintains color
Canning salt helps preserve the natural color of vegetables.
Dissolves easily
Its fine texture makes it perfect for brines and even mixing.
Consistent results
You get more predictable, reliable canning results.

Common Questions
