Kosher Salt vs. Sea Salt: What’s the Real Difference?
When it comes to cooking, not all salt is created equal. Walk down any grocery aisle and you’ll find a variety of salts: iodized table salt, Himalayan pink salt, flaky salt, kosher salt, and sea salt. Two of the most commonly confused varieties are kosher salt and sea salt. Though they may look similar in the shaker, these salts vary significantly in texture, origin, processing, and culinary use. So which should you be using—and when?
Let’s break it down.
🧂 What Is Kosher Salt?
Kosher salt is a coarse-grained salt named for its traditional use in the koshering process of meats (drawing out blood to meet Jewish dietary laws). However, it has become a go-to salt for chefs and home cooks alike.
Key Characteristics:
Texture: Large, flaky crystals
Taste: Pure salty flavor, no additives
Origin: Typically mined from underground salt deposits
Processing: Minimal, without iodine or anti-caking agents
🌊 What Is Sea Salt?
Sea salt is produced by evaporating seawater. It’s available in various textures and grain sizes, depending on where and how it’s harvested.
Key Characteristics:
Texture: Ranges from fine to coarse; often flaky
Taste: May contain subtle mineral flavors
Origin: Evaporated from seawater, usually in coastal regions
Processing: Minimal or no refining; may retain trace minerals

You’re seasoning meat (great for grip and distribution)
Cooking large batches (easy to pinch and control)
Wanting a quick dissolve in water (Diamond Crystal is especially good for this)
Avoiding added iodine or chemicals in your food
✅ Use Sea Salt When:
Finishing a dish with a flavorful crunch (e.g., salads, steaks, caramels)
Enhancing presentation (adds visual appeal)

Looking for subtle minerality or regional character in your salt

🧪 Why Texture and Volume Matter in Cooking
Not all salts weigh the same. A teaspoon of Diamond Crystal kosher salt weighs less than a teaspoon of Morton kosher salt, and both weigh significantly less than sea salt or table salt.
| Salt Type | 1 Teaspoon = Approx. Weight |
|---|---|
| Diamond Crystal Kosher | 2.8 grams |
| Morton Kosher | 4.8 grams |
| Fine Sea Salt | 6.0 grams |
| Table Salt | 6.0 grams |
🌍 Environmental and Ethical Considerations
Both sea salt and kosher salt can be produced sustainably, but they have different environmental footprints.
| Factor | Kosher Salt | Sea Salt |
|---|---|---|
| Energy Use | Often mined with mechanical equipment | Uses sun and wind for evaporation |
| Natural Resources | Extracted from land deposits | Harvested from ocean water |
| Regional Variants | Mostly U.S.-based | Available from multiple global regions |

🧑🍳 The Final Verdict: Which One Should You Use?
Choose kosher salt for everyday cooking. Its texture makes it easy to handle, and it provides consistent flavor.
Choose sea salt for finishing dishes and adding gourmet flair. The texture and trace minerals offer a unique culinary experience.
