I’ve been using Diamond Crystal Kosher Salt—famously known as the ‘red box’—to season my food since I got married and started cooking for my family. It is hands-down the best salt and my go-to in everyday cooking.
And I’m certainly not alone. Countless professional chefs and avid home cooks are equally loyal to its superior flavor and performance. The most famous advocate of Diamond Crystal has to be chef and author Samin Nosrat, who wrote in her best-selling book Salt, Fat, Acid, Heat: “It has a greater impact on flavor than any other ingredient.”
Yes, it is “just salt”—but as I’ve always believed, quality ingredients make all the difference in your cooking.
Since readers often ask why I specifically reach for this kosher salt in my recipes, I thought it was time to dedicate a post to Diamond Crystal and share what sets it apart.

What’s So Special about Diamond Crystal Kosher Salt?
Balanced Flavor and Most Forgiving
Unlike dense table salt, Diamond Crystal’s hollow, light structure means it contains significantly less sodium by volume. It strikes a ideal balance: enhancing natural flavors rather than overpowering them. This is the biggest difference you’ll notice as soon as you make the switch.
For delicate cuisines like Japanese food, salt should draw out natural flavors without making dishes taste harsh or overly salty. Its forgiving nature allows you to season confidently across savory dishes and sweet treats alike, with far less worry of accidentally over-salting.
Exceptional Purity
One of the main reasons I love Diamond Crystal is its complete lack of additives. Unlike many standard table salts or heavily processed brands, it consists of 100% pure salt—free from iodine, anti-caking agents, or chemical additives.
It is crafted by evaporating Pacific seawater through a specialized process without mechanical compaction, resulting in clean, pure salt crystals. You can learn more about their patented Alberger process here.
Unique Flake Texture
Diamond Crystal’s defining feature is its hollow, pyramid-shaped flake texture. These light, irregular flakes dissolve quickly, distributing saltiness evenly throughout a dish. Because the crystals are light and flaky rather than hard granules, they cling to ingredients much better—meaning your seasoning stays on the food instead of bouncing off into the pan.
This delicate texture is especially beneficial for baking, where precise flavor distribution is critical. It also makes intuitive seasoning effortless. When you season by hand using the “pinch and sprinkle” method favored by chefs, the light flakes give you total control over every dish.

Ways to Use Diamond Crystal Kosher Salt
Because of its light texture and fast-dissolving nature, Diamond Crystal Kosher Salt is incredibly versatile in everyday cooking:
- Everyday Seasoning: Perfect for roasting vegetables, blanching vegetables, making quick pickles, oven-baking meat, seasoning fish or chicken wings.
- Brining & Pickling: Ideal for making quick pickles or brining meats, as it dissolves rapidly in liquids.
- Pasta & Boiling Water: Use it generously for salting pasta water—its lighter density gives you a wider safety margin against over-salting.
- Rubs & Snacks: The fine, sticky flakes cling exceptionally well to ingredients, making it the perfect base for homemade dry rub or seasoning freshly popped popcorn.
General Recipe Guidelines
- American Recipes: Most U.S. recipes call for kosher salt. Unless a recipe explicitly specifies “table salt” or “sea salt,” follow the measurement provided for kosher salt.
- Season to Taste: Salt preference is highly personal, and brand densities vary. Always taste your food as you cook and adjust seasonings to your liking. If you are ever unsure, start with a smaller amount—you can always add more salt, but you can’t take it away!
Where to Buy Diamond Crystal Kosher Salt
I typically pick up my Diamond Crystal Kosher Salt at local Bay Area supermarkets. If you can’t find it at your local grocery store, here are a few other reliable places to check:
- Online: You can easily order it online from Amazon or directly from restaurant supply stores.
- Specialty & Restaurant Supply Stores: Check local gourmet food shops, which almost always keep it in stock.

FAQ
What’s the difference between Diamond Crystal and Morton Kosher Salt?
Both Diamond Crystal and Morton are two popular brands of kosher salt. Most people are probably more familiar with Morton’s as it is readily available (it’s also cheaper), but it contains an anti-caking agent. Diamond Crystal may not be available everywhere, but you can find it online or even at select Trader Joe’s these days.
Diamond Crystal is less salty in taste and more crumbly in texture, whereas Morton is much saltier and denser. I personally find that Diamond Crystal dissolves much quicker than Morton, so you don’t have to worry about over-seasoning.
Both salts also have different shapes! The salt crystals for Diamond Crystal are lighter and have a hollow structure, allowing you to crush the salt easily with your fingers, making it easy to crush the salt.
How about table salt? How does it differ from kosher salt?
There are two main visible differences. First, kosher salt has larger flakes than table salt, which is made of many fine salt granules. Second, kosher salt is pure sodium chloride, whereas most table salt is “iodized,” meaning it contains added iodine. Table salt also typically contains anti-caking agents.
Do you use the kosher salt for finishing, too?
I primarily use kosher salt as my cooking salt, meaning I add it during the cooking process. For finishing or sprinkling at the table, I prefer Maldon sea salt, Himalayan pink salt, or flavored salts—they add a nice texture and a touch of extra flavor.
