The Full Story

Unlike sugar, salt is incredibly deceptive to measure by volume. A level teaspoon of standard, fine table salt weighs about 6 grams. However, if you scoop a teaspoon of coarse sea salt, it will only weigh 4 to 5 grams. If you use large, pyramid-shaped flaked sea salt, a teaspoon might weigh as little as 2 to 3 grams. The larger the crystal, the more empty air space sits in the spoon.

This 6-gram measurement is critical for your health. Both the NHS and the World Health Organization state that adults should consume no more than 6 grams of salt per day (and children only 3 grams). It is important to note the difference between salt and sodium: 6 grams of salt contains exactly 2.4 grams of sodium.

You might think you don't add a whole teaspoon of salt to your meals, but you probably don't need to. Roughly 75% of the salt we consume is already hidden in everyday processed foods like bread, breakfast cereals, and ready meals. Have you ever wondered why professional recipes often say "season to taste" instead of giving an exact measurement? Because depending on the brand and crystal size of the salt you use, your teaspoon could be 50% saltier than the chef's.

Did You Know?

Bread is a major source of hidden salt. A single slice of commercially baked bread can contain between 0.5 and 1 gram of salt. A simple sandwich could account for a third of your daily limit before you even add the filling.

Flaked salt tastes saltier, but contains less salt. Because flaked salt (like Maldon) has a large surface area, it hits your tongue and dissolves rapidly, giving a massive burst of salty flavour despite weighing significantly less per pinch than table salt.

Iodised salt was a public health miracle. In the 1920s, governments began adding iodine to table salt to prevent goitre (enlarged thyroid glands) and developmental issues, effectively eradicating the deficiency in developed nations.

Fine Salt vs Sea Salt vs Flakes — Does It Actually Matter?

In the culinary world, salt is not just salt. The physical shape of the crystal completely changes how it interacts with food and your palate. Fine table salt is dense and dissolves instantly. It is perfect for baking (where precise chemical reactions are needed) or heavily salting a pot of boiling pasta water.

Kosher salt is the chef's best friend. Its irregular, medium-sized grains are easy to pinch between your fingers, allowing for precise, tactile seasoning over a piece of meat. Because it is less dense than table salt, it is much harder to accidentally over-salt a dish.

Then there is finishing salt, like Maldon sea salt flakes. These hollow, pyramid-shaped crystals are never used during the cooking process because they would just dissolve and lose their magic. Instead, they are sprinkled over a finished steak, a fresh tomato salad, or a chocolate chip cookie right before serving. They provide a satisfying crunch and a bright, clean burst of salinity that elevates the entire dish.
