Kosher Salt vs. Sea Salt

August 31st, 2020

You can’t cook without salt. Professional chefs and home cooks know this to be true, but which salt is best, and what is the difference between kosher salt and sea salt? These are two of the most popular salts in recipes, but they’re not always interchangeable. Keep reading to learn when to add a pinch of kosher salt to your dish, and when to reach for sea salt.

What Is Kosher Salt?

Kosher salt starts out as sea water, which leaves crystals behind when water evaporates. Where kosher salt differs from sea salt is in flake size. Kosher salt crystals are larger and rougher in texture than many other salt crystals, which is why chefs like Thomas Keller use it throughout the cooking process, but “save the flaky crunch and light clean flavor of Maldon sea salt for finishing.”

History of Kosher Salt

Today’s kosher salt isn’t technically a kosher food (unless it’s processed and labeled as such), but it has origins in the Jewish culinary tradition of removing the blood from meat. Koshering salt had larger crystals that help draw the liquid from meat, and was easier to rinse off afterwards.

Is Kosher Salt Iodized?

Kosher salt is not iodized. Because it doesn’t have iodine (which can add a bitter taste to foods), kosher salt is considered to be superior to table salt when it comes to seasoning foods.

What Is Kosher Salt Used For?

Why cook with kosher salt? Both professional chefs and home cooks trust kosher salt in the kitchen as a must-have ingredient because it’s easy to pinch and offers consistent, clean flavor. In addition to seasoning recipes while cooking, here are a few more suggestions for how to use kosher salt:

  • Salt pasta water
  • Brine meats
  • Create dry rubs
  • Salt the rim of a margarita glass

What Is Sea Salt?

As the name suggests, sea salt is sourced from bodies of water. The most popular location is the Mediterranean, but sea salt companies can be found all over the world and coast to coast, from Oregon to Cape Cod.

How Is Sea Salt Harvested?

From small family businesses to larger operations, sea salt harvesting can range in scale. In general, the journey from water to your kitchen starts with shallow ponds. As sun and wind do their work, the water evaporates and leaves behind white salt crystals. Harvesters scoop salt and transfer it to an area where it’s rinsed and cleaned. Fun fact: sea salt can take on various hues (like pink) based on the different types of clay or algae that may be present in the water.

Sea Salt In Cooking

Sea salt can be used like kosher salt to season ingredients, but its coarser texture and unique flavor is often better suited for adding a finishing touch (like sprinkling on a batch of chocolate chip cookies or enhancing grilled fish, for example). As Fine Cooking shares, sea salts are most commonly used just before serving a dish. “Their flavor nuances and distinct colors and textures are apt to be lost when added during the cooking process; plus, they’re expensive to pour into the pasta pot.”

In addition to seasoning food, there myriad ways to use sea salt in the kitchen and around the house. Here are some ways to use it:

  • Clean cast iron pans: The flakes act as a gentle abrasive to absorb grease and wipe pans clean.
  • Remove fish smells: Similar to baking soda, sea salt has odor-absorbing properties that works wonders on your cutting boards.
  • Make a DIY body scrub: Just add sea salt, an oil (like jojoba or coconut oil), and your favorite essential oils for a soothing scrub to leave skin feeling smooth.
  • Draw a foot bath: Soak tired feet in a sea salt and water bath for instant invigoration.
  • Soothe a sore throat: Gargling with a warm water and sea salt tonic is believed to help ease symptoms of a sore throat.
