If you are wondering where to buy fleur de sel, look no further. This salt is one of the most popular sea salts available. The crystalline form makes it much finer than Maldon sea salt. It has a similar volume, but a slightly stronger flavor. Generally, you should use 1/2 teaspoon for every cup of water. Its light texture and delicate snow texture make it an excellent choice for baking. You can even use it to season candies and other baked goods.
