Flake salt

Flake salt is a type of salt made up of large, thin, irregular flakes. It is typically produced by boiling brine and then allowing the salt crystals to form into flat flakes, often through a process called the 'fleur de sel' method. This method results in a delicate texture and a clean, pure saline taste.

Manufacturers use flake salt primarily for its texture and flavour-enhancing properties. Its large flakes provide a satisfying crunch and a burst of saltiness when sprinkled on food. It is often used as a finishing salt on baked goods, meats, salads, and chocolate confectionery to add both visual appeal and a distinct salty note.

Salt (sodium chloride) is a permitted food additive in the UK, listed on the Register of Food Additive Authorisations. The UK's Scientific Advisory Committee on Nutrition (SACN) recommends that adults consume no more than 6g of salt per day, which equates to about 2.4g of sodium. Excessive salt intake is associated with increased blood pressure, according to the NHS. Evidence regarding the health impacts of salt is extensive and well-established.
