FLAVOUR & SAVOUR |How To Choose The Right Type Of Salt For Your Recipe

In a world history of food and cooking, salt is the most universal ingredient. Sweet, savory, meat, vegetable, in the background or in your face, there is salt.

“Salt is the single most important ingredient in cooking and the single most powerful tool for improving the flavor of food”, says Mark Bitterman in his encyclopedic book, “Salted”.

So it’s no wonder that you may experience decision paralysis when it comes time to select a salt from the grocery shelf or your pantry. Or you may take the exact opposite approach and giving absolutely zero thought to this staple ingredient.

Here’s why it matters and what you should consider.

Know The Types

There are four types of salt that most home cooks use on a regular basis: table, kosher, sea and finishing. The good news? They’re all essentially chemically identical – as in salt, or sodium chloride. The difference boil down to how they’re made, their shape and, depending on whom you ask, their flavor.

  • Table salt is granulated with a fine texture consisting of small cubes. It often includes potassium iodide to provide iodine (more on that later) and an anti-caking agent to keep crystals from sticking to each other, Harold McGee writes in “Keys to Good Cooking”.
  • Kosher salt consists of larger, flakier crystals, named because of its ability to help extract blood and moisture out of meat during the koshering process of Jewish dietary law. It is not iodized.
  • Sea salt can be more or less refined than other types, with smaller or larger crystals. It may feature additional mineral that impart a  bitter flavor, McGee says.
  • Finishing salts often boast pedigree of sourcing and can come in a wide array of shapes and colors.

Understand Why The Shape And Size Matters

“The type of salt can make a major difference in how well it blends in. flakey sea salt and Diamond Crystal brand kosher salt blend faster and better than granular table salt”, Shirley Corriher writes in “BakeWise”. That has to do with how each type of salt is formed. Corriher points out that 90 percent of a granular salt will bounce off a surface while 95 percent of a hollow flaky salt will stick, not to mention dissolve faster. Both factors are major reasons chefs and cookbook authors often express a preference for Diamond Crystal, which is a hollow flake pyramid. Other kosher salts, such as the common Morton’s coarse salt, are formed when granular salt is flattened by rollers, according to Corriher. She favors sea salt for baking (she advocated grinding Maldon as needed), as does Rose Levy Beranbaum, who is “The Baking Bible” notes that “it ingrates more readily into batter than does a coarse salt”. One other factor to consider: Kosher salt is easier to pinch, pick up and see when you’re, say, seasoning meat. Koser salt also makes for a clear brine.

In “The Food Lab”, J.Kenji Lopez-Alt calls kosher salt the “only one you absolutely need in your kitchen”. If you’re concerned about iodine deficiency, know that plenty  of foods, including dairy, seafood and vegetables, include iodine.

Understand The Flavor

Here’s where things get fuzzy. Do different salts taste different? Depends whom you ask. Bitterman, a writer and gourment food shop owner who calls himself the world’s first “selmelier”, is adamant that they do. He has little use for grocery store salt, describing the flavor of table salt as “drying spray paint, dirt, fishhooks”, kosher salt as “hot, bright, sometimes metallic and/or faintly acrid” and sea salt as “sharp flatness”. Needless to say, he doesn’t recommend using any of them in home cooking.

I fall into the same camp as McGee, who Says, “All salts without added flavors taste about the same, especially in food. Exotic origins can be very interesting to the mind but don’t register on the plate”.

If you’re baking, Beranbaun cautions against using iodized table salt, which she say can impart an “unpleasant taste”.

Do what also makes economic sense. Don’t burn your fancy designer salt on pasta water.

Figure Out How Much You Need

Ideally, recipes will specify what type or brand of salt to use. Otherwise, McGee recommends starting with a smaller amount and increasing according to taste. If you want to change the type specified, keep in mind the uses and characteristics above. Says Corriher: “To get as much salt as there is in 1 tablespoon of granular salt, one must use 1 ½ tablespoons of Morton’s kosher salt or 2 tablespoons of Diamond Crystal kosher salt”. And keep in mind a tablespoon of each type of salt will have a different weight based on the size of the crystals and how densely they’re packed in the measuring spoon.

Emphasize The Finish

For most of us, this is where to get the most bang for your buck with more expensive specialty salts. “Finishing with salt is the linchpin of strategic salting; it’s a versatile cooking technique and one of the most effective ways we have of playing sensually with what we eat”, Bitterman writes. “The practice of finishing with salt is straightforward: choose an artisan salt, scatter it across the surface of your food, and eat.”

Think about color and texture here, whether you want something that will contrast or complement the food. Finishing salts can be a variety of shapes, from delicate flake to crunchy crystals. Or male your own flavored topper, combining salt with herbs, spices or citrus zest.

Whatever, you choose, season the food at serving temperature, McGee says. Hot food can heighten a variety of flavors, including saltiness.
