The Difference Between Morton’s and Diamond Crystal Kosher Salt
Why Kosher Salt Brand Matters: Unpacking the Crucial Differences for Better Cooking Results
The Not-So-Secret Difference Between Morton’s and Diamond Crystal Kosher Salt
When scanning a recipe that calls for kosher salt, most cooks assume that any box labeled “kosher” will yield the same result. But if you’ve ever ruined a dish by accidentally over-salting (or under-seasoning) after swapping brands, you may have learned the hard way: not all kosher salts are made alike. Specifically, Morton’s and Diamond Crystal, the two giants of the kosher salt aisle, behave differently in your kitchen. This difference has far-reaching consequences in flavor, texture, and overall outcomes for your culinary creations.

A Crash Course: Salt Anatomy 101
Kosher salt isn’t simply salt that’s been blessed for religious purposes; it actually describes a coarser, flaked salt that was originally used for koshering meat by drawing out blood. Yet among kosher salts, subtle distinctions in shape, size, and density can dramatically alter how salty your food tastes.
The two major brands in the U.S. are Diamond Crystal and Morton’s. Both are labeled “kosher salt,” but beneath the box, their salts couldn’t be less identical.
The Origins and Methods Behind the Brands
Diamond Crystal and Morton’s take very different paths from brine to box. Each method leaves a lasting fingerprint on the qualities of the salt you shake over your food.
- Diamond Crystal: Created using the patented Alberger process, in which saltwater forms hollow, pyramid-shaped flakes as it evaporates in open containers. This results in super-light, airy crystals that crush easily between your fingers.
- Morton’s: Produced by crushing cubic grains of salt into dense, flat flakes through high-pressure rollers. Morton’s flakes are denser, heavier, and more tightly packed.
Why does this matter? Because the structure and density affect not only how salt feels and dissolves, but also how salted your food tastes for the same measured volume.
| Brand | Production Method | Crystal Shape | Texture | Saltiness Per Teaspoon |
|---|---|---|---|---|
| Diamond Crystal | Alberger evaporative process | Hollow pyramids | Light, flaky, crushable | Milder/less salty |
| Morton’s | Rolled and flattened cubes | Dense, thick flakes | Heavy, grainy, slow to dissolve | Much saltier (per tsp) |
Morton’s vs Diamond Crystal: A Side-By-Side Comparison
The brand differences aren’t just theoretical—the crystals literally look and feel different in your hand, and they season food in dramatically different ways.
- Diamond Crystal’s pyramid-shaped crystals: Larger and more airy, so a spoonful contains more “air space” and less actual salt per spoonful.
- Morton’s compact flakes: Smaller, denser, and heavier. A given “pinch” or teaspoon will deliver much more salt to your dish.
In practice, one teaspoon of Morton’s can almost double the saltiness of a teaspoon of Diamond Crystal! That’s why a simple substitution can make the difference between a perfectly seasoned meal and a mouthful of brine.
Why the Difference Matters in Cooking & Baking
Why care which kosher salt you use? Because recipes aren’t written in a vacuum: they often assume a particular brand. Swap one for the other without adjusting, and outcomes change dramatically.
- Saltiness varies dramatically: Diamond Crystal contains 53% less sodium per volume compared to table salt. Morton’s is denser, so it’s saltier for the same amount.
- Texture and dissolution affect seasoning: Diamond Crystal dissolves faster and adheres better, so it seasons more evenly. Morton’s can clump or sit on the surface, making it easier to over-salt or miss spots.
- Visual difference is real: With Diamond Crystal, there’s more “space” between crystals, making it less likely you’ll over-salt when seasoning by hand.
- Better for finishing touches: Diamond Crystal’s lighter flakes make it a favorite for final seasoning on steaks, vegetables, and baked goods. Morton’s is sometimes criticized for a “rocky,” gritty crunch in these applications.
- Baking is especially sensitive: In doughs or batters, where salt needs to dissolve and distribute, using a denser salt without adjusting weight can unbalance flavor and texture.
Kosher Salt Conversion Guide
If a recipe doesn’t specify which brand, the risk of over- or under-salting is high. Fortunately, experts have published conversion ratios based on weight:
- Jill Santopietro (Chowhound) conversion: 1 1/4 teaspoons Morton’s ≈ 1 3/4 teaspoons Diamond Crystal
- Edward Schneider (NY Times) conversion: 1 teaspoon Morton’s ≈ 1.85 teaspoons Diamond Crystal
- General Rule: Morton’s and fine salt are roughly equivalent by volume. To substitute Diamond Crystal for Morton’s, use nearly twice as much.
Table for Quick Reference:
| Recipe Calls For | If Using Morton’s | If Using Diamond Crystal |
|---|---|---|
| 1 tsp kosher salt | 1 tsp Morton’s = very salty | ~1.75 tsp Diamond Crystal = less salty |
| 1 tsp Diamond Crystal | ~0.6 tsp Morton’s | 1 tsp Diamond Crystal |
| 1 tsp Morton’s | 1 tsp Morton’s | ~1.8 tsp Diamond Crystal |
Remember: when in doubt, season conservatively and add more salt if needed. It’s far easier to add than to remove excess salt.
What Culinary Experts Say
Few chefs have better articulated the differences than Samin Nosrat, author of Salt, Fat, Acid, Heat:
- She describes Diamond Crystal as “less salty and more crumbly,” and Morton’s as “much saltier and denser.”
- Nosrat insists that Diamond Crystal dissolves faster and sticks to food better, preventing seasoning mishaps like salt falling off meat in the pan.
- Her advocacy reportedly helped save Diamond Crystal’s large, three-pound box from discontinuation, attesting to its cult status among professionals.
Other food writers echo her experience:
- Edward Schneider (NY Times): Switching unknowingly from Diamond to Morton’s ruined his salt “instincts,” resulting in constant over-salting of everything from pasta to pound cake.
- Smitten Kitchen’s Deb Perelman: “Pretend they used Diamond salt.” She recommends starting with Diamond Crystal quantities as a default and adjusting upward if needed.
Tips for Home Cooks
- Always check which salt a recipe author intended. Many popular cookbooks and test kitchens use Diamond Crystal; when in doubt, start there.
- Don’t swap one for the other 1:1. If you must use Morton’s, reduce the amount compared to Diamond Crystal, and vice versa if switching in the other direction.
- Weigh your salt for baking. Owing to volume differences, weighing ensures accuracy and repeatable results, especially in breads and pastries.
- Salt dissolves faster in water than in oil. For salad dressings, dissolve your salt in vinegar or lemon juice first to avoid a sandy, uneven texture.
- Adjust to taste. Add gradually and taste as you go, especially when switching brands or styles of salt mid-recipe.
Frequently Asked Questions (FAQs)
Q: Can I substitute Morton’s for Diamond Crystal in any recipe?
A: No, direct substitution will lead to overseasoning because Morton’s is denser and saltier by volume. Always use less, or consult a conversion chart.
Q: Why doesn’t every recipe specify which brand of kosher salt to use?
A: Many recipe developers assume their readers use the same salt they do (often Diamond Crystal), but not specifying can result in widely varying results at home.
Q: What should I do if my store only has Morton’s?
A: Use about 60% of the volume called for Diamond Crystal in the recipe. Or better yet, weigh your salt whenever possible for consistency.
Q: Is it ever okay to use table salt instead?
A: Table salt is even denser and “saltier” than both kosher salts by volume. If you substitute, use about half the amount by volume (but beware: table salt often contains anti-caking agents that can alter flavor and texture in some recipes).
Q: What’s the best salt for finishing dishes?
A: Diamond Crystal’s light, flaky texture makes it ideal for finishing, as it adheres well and dissolves quickly. Morton’s can leave gritty spots, while fine sea salt is more delicate but also more expensive.
Final Thoughts: The Takeaway for Every Cook
The choice between Diamond Crystal and Morton’s kosher salt is more than just a matter of brand loyalty. Understanding their differences can make the difference between a perfectly seasoned masterpiece and a culinary misstep. Choose wisely, use conversion guides, and above all, taste as you cook—your food will thank you!
