How to choose the right type of salt when cooking at home, according to chefs
Can you substitute table salt for kosher salt? All your questions, answered.
This is textbook table salt from one of the most prominent brands you’ll see when shopping for groceries online or in stores, according to our experts. It contains anti-caking agents and iodide.
Kosher salt granules are large in size, coarse in texture and irregular in shape, giving its crystals a lot of surface area. This makes it easy to pick up with your hands and control distribution while sprinkling it over food, says Shawn Matijevich, the lead chef-instructor for the Institute of Culinary Education’s online culinary arts and food operations program. Kosher salt takes longer to dissolve compared to table salt since its crystals are large in size, so you can easily see spots you missed when you season vegetables, fish and meats, says Arnone. Our experts recommend using kosher salts for brines because of this.
All of the chefs we interviewed say kosher salt is their preferred variety for any type of savory cooking. It doesn’t have additives like iodine (which some people find metallic tasting), instead it has a nice, clean flavor, says Matijevich. Despite its name, not all kosher salt is Kosher certified. Instead, it’s called kosher salt because its large crystal size has long been preferred by chefs in the Jewish community for koshering meat, a process that involves drawing blood and other impurities out of raw meat. Only kosher salt that has the OU Kosher certified logo on its label is kosher certified.
“I use Diamond Crystal kosher salt for all of my cooking purposes at home or in the restaurant,” says Hartman. And if he had to estimate, Matijevich says Diamond Crystal is the type of kosher salt 90% of professional chefs use because of the clean flavor and since its crystals are so easy to pick up with your hands. Diamond Crystal Kosher Salt is kosher certified, according to the brand.
While table salt and kosher salt are mined from rock-salt deposits, sea salt is harvested through evaporating seawater. It’s minimally processed, which means it retains more of its natural minerals compared to table salt and kosher salt, giving it a more intense, prominent taste, says Angela. Sea salt has a coarser grain than table salt and it’s softer than kosher salt, which means it’s crunchy and dissolves slowly, says Verzeroli.
Arnone recommends using sea salt as a finishing salt, meaning one you sprinkle over dishes right before you serve them. This allows you to see the crystals on food — especially if they’re colored — get the full intensity of its flavor and enjoy its crunch. That doesn’t mean you can’t cook with sea salt — just do so intentionally, says Arnone. “For example, if you’re making a beurre blanc sauce to go over seafood, you might want to capitalize on that sea flavor and incorporate sea salt into it,” he says.
There are different types of sea salt, which come from a specific region — certain ones are not better than others, what you like comes down to a matter of personal preference. Some are also colored due to ingredients they’re mixed with or minerals they naturally contain. For example, sea salt that’s black in color is usually mixed with activated charcoal.
Maldon is a company based in Maldon, Essex (United Kingdom) and it harvests its sea salt flakes from a small body of water in the coastal town. Like any type of salt, Maldon’s accentuates the natural flavors of food, but experts consider it special due to its pyramid-shaped crystals that are large, delicate and thin. Maldon sea salt also has an extra crunchy texture, making it an ideal finishing salt, experts told us.
Other brands sell sea salt flakes, but Maldon’s are generally the most highly regarded among experts and home cooks alike. They’re so popular that many people refer to sea salt flakes as “Maldon,” similar to how some refer to tissues as “Kleenex.”
“For a finishing salt, I always choose a natural, high-end salt with bigger crystals like Maldon,” says Verzeroli. I think of it like jewelry for food since it essentially accessorizes a dish. You can sprinkle it over a sliced roast before serving it, or make chocolate chip cookies, caramels and chocolate bonbons extra special by adding some on top.
Maldon salt is available in an 8.5-ounce carton, as well as a 20-ounce bucket, which I highly recommend investing in. I sprinkle the sea salt flakes over pretty much anything I cook, so buying the bucket ensures I don’t run out for months. It’s also a great gift for hosts and aspiring bakers — pop a bow on top, add a card and you’re set.
Fleur de Sel is very similar to Maldon sea salt and also has delicate pyramid-shaped crystals. But it’s harvested by hand in parts of France off the Atlantic coast, resulting in an ultra-clean, mineral-rich, very salty taste, says Hartman. “This type of salt is a favorite of many culinary professionals as a final finishing touch just before serving a dish to guests,” says Angela. “It has a delicate, light crunch and, when used in correct amounts, elevates the flavor of a meal.”
Himalayan pink salt is harvested in areas near Pakistan’s Punjab region and has minerals like magnesium, potassium, iron and zinc, giving it its pink hue, says Angela. Compared to sea salt, it’s milder in taste and has an earthiness to it. You can cook with pink Himalayan salt like you would table salt or kosher salt, and some people favor it because it has minerals they want to incorporate into their diets, like magnesium, calcium, iron and zinc, says Matijevich.
In addition to ground pink Himalayan salt, it’s available in blocks you can use as a cooking surface or serving tray for meat, fish and vegetables, says Angela. The blocks evenly distribute heat and infuse a bit of salt into the ingredients resting on top of them, lightly seasoning food. Pink Himalayan salt blocks are also reusable, and you can typically cook with them in the oven, on grills, over stove tops and over open fires.
Smoked salt is almost always sea salt that’s undergone a cold smoking process, says Arnone. Sea salt’s large crystal size helps smoke stick to it better than other types of salt. You should exclusively use it as a finishing salt to preserve its taste, and you can sprinkle it over almost any food to introduce an additional flavor element, says Arnone. He particularly likes using smoked salt to enhance vegetarian and vegan dishes, but you can also add it to meat you don’t want to spend time smoking, or as a dry rub to create depth of flavor.
Maldon, one of our experts’ favorite brands, smokes its sea salt flakes over English oak wood. You can purchase the flakes in a 1.1-pound tub or a 4.4-ounce carton.
Flavored salts have spices, herbs or dried fruit zests incorporated into them, and using them lets you season food while adding complementary flavors to it, experts told us. For example, you might see salt mixed with garlic powder, lemon zest or herbs like rosemary, thyme and oregano. You can buy flavored salt or make small batches of it at home by following recipes available online and in cookbooks.
You typically would not use flavored salts on a regular basis, but it’s handy to keep one or two at home that pair with foods you commonly eat. Those who frequently barbeque may find a salt flavored with rosemary and black pepper useful for adding to dry rubs, meat and poultry, says Arnone. I always keep garlic salt in my kitchen to sprinkle over vegetables and fish — ingredients I use to make dinner almost every day.
There’s no perfect science to seasoning food with salt since a lot of it has to do with your taste preferences. But here are a few expert tips to keep in mind while cooking.
You can use table salt as a substitute for kosher salt, and vice versa, but you’ll have to adjust the measurements of your recipe, says Matijevich. Table salt crystals are smaller than kosher salt crystals, so they’re more densely packed. That means if a recipe calls for one teaspoon of table salt, you might need two (or more) teaspoons of kosher salt to get the same level of “saltiness.” If you’re going to substitute one type of salt for the other, it’s best to follow a 1:2 ratio of table salt to kosher salt. Then, frequently taste your food as it's cooking and add a pinch of salt here and there as you see fit, experts told us.
Keep in mind that substituting one type of salt for the other is safest during cooking, not baking. “Baking and pastry are formula-based, so stick to the formula,” says Arnone. “You have more latitude with cooking, so making a minor adjustment won’t ruin a recipe.”
The finer the salt, the easier it will dissolve and melt while cooking and baking, says Verzeroli. And since it’s so small, fine salt fits through the little holes on the top of salt shakers.
Coarse salt, on the other hand, dissolves slowly, even when heat is applied. That’s why it’s favored as a finishing salt, adding a crunchy texture to dishes and allowing you to easily see how much you’re using at one time. Coarse salt won’t fit through a salt shaker’s holes, so you can put it inside a grinder instead to easily dispense it.
“Like wine and olive oil, salt has beautiful nuances in flavors based on how and where it has been harvested,” says Verzeroli. But these nuances are subtle, and some people notice them more than others depending on their taste palate. If you’re interested in learning about which regional flavors you gravitate toward, try a few options on the same type of food and compare them.
Because the majority of home chefs have kosher salt in their kitchens, many recipes online and in cookbooks call for it. However, while baking, our experts generally prefer using table salt due to its small, fine crystal size. “You get better dispersion in the mix, and the smaller pieces dissolve into the batter faster,” says Arnone. Kosher salt’s large crystal size also often doesn't fit through a sifter, a baking tool that breaks up clumps of dry ingredients, says Matijevich.
While table salt is best for mixing into a baked goods’ batter or dough, you can sprinkle kosher salt or flakey sea salt on top of pastries, chocolates and other desserts as a finishing touch, says Angela.
Heavily salting pasta water before cooking any type of noodle is crucial to bringing out its flavor, says Hartman. “Without any salt in your cooking water, you'll be left with a very bland noodle, and it's difficult to recover from that,” he says. Hartman recommends salting pasta water with kosher salt since it’s likely what you’ll be using for the rest of your savory cooking, but overall, any non-iodized cooking salt will do the trick. So that means if you’re going to use table salt, double check the ingredient label to ensure the brand didn't add any iodide.
Beyond the type of salt you use, when you salt pasta water is also key. “It's important to only add the salt to your pasta water once it has come to a boil,” says Hartman. “Adding salt too early, before the water has boiled, may result in your pot getting scratched from the undissolved salt particles.”
You can measure salt by volume using measuring spoons and cups, or by weight using a scale. Regardless of what you’re measuring, doing so by weight is more accurate, but most recipes give measurements in teaspoons, tablespoons and cups because the typical home cook doesn't own a kitchen scale, says Hartman. If you’re following a recipe, use the type of salt specified and do not convert it from weight to teaspoons, tablespoons and cups (and vice versa) when possible, experts told us. That’s the best way to ensure you get the intended final result. But if you’re not following a recipe, seasoning food with salt to taste is your best bet since it allows you to customize the flavor according to your preferences.
No, salt does not expire and pure salt can last a long time. But if it’s stored improperly, salt can absorb moisture and clump together, experts told us. With that said, be sure to inspect your salt before you use it, looking for changes in color and texture that may alert you to a decline in quality.
Keep in mind that flavored salts typically have a shorter shelf life compared to pure salts due to the additional ingredients they’re made with, says Verzeroli. Over time, flavored salts lose their flavors, so take note of the “best by” date on a product’s packaging.
“Humidity and odor are the enemy of salt,” says Verzeroli. It can absorb moisture and clump together, as well as absorb odors from strong spices stored nearby. To keep salt as fresh as possible, store it in a cool, dry place and in a sealed container, says Arnone.
Many brands sell salt in paperboard boxes, and if you keep them in a moist environment (like next to the sink), they’ll quickly absorb moisture and the salt will start to clump. You can consider transferring your salt to a lidded glass, plastic, marble or wood container as these materials provide extra protection against moisture, experts told us. I keep my kosher salt in a mason jar with a tightly fitting lid, but you can also purchase a salt cellar, a crock specifically designed for storing salt with an opening large enough for you to grab a pinch (or more) while seasoning.
