While many may believe the black truffle to be a very rare delicacy, this is simply not true. Black truffles are an extremely common type of fungus that grows on plants, such as grapes.
Many people say that black truffles have to be ground up before they can be consumed. While this is indeed true, the chances of you being able to find a "truffle salt" factory that grinds these mushrooms into a fine powder are rather slim. The reason is that it takes a long time for the stones formed by the truffles to sink down to the bottom of the grind.
In reality, it's far more cost-effective to simply get a nice brand of truffle salt for your table and to go from there. Using just a little black truffle sea salt may help you achieve the right taste. You'll likely want to experiment with different brands to see which one produces the best results for you.
A more economical option is to use black truffle salt in place of your white table salt. This might seem like a strange practice, but it actually works quite well and it's actually cheaper to use than using sea salt if you buy the cheap brands, rather than the expensive ones.
The key is to ensure that the black truffle salt you use is not a black colored, but rather a brownish gray. Another key factor is to avoid the black crystals which can result from the grinding process. They will detract from the taste, as well as reduce the shelf life of the salt.
Some manufacturers produce a kind of black truffle salt, which is really a variation of sea salt but is black in color. There are a number of variations of black truffle salt.
Whatever black truffle salt you use, you need to be sure that it is, in fact, black and not gray or brown. There are a number of sites that sell salt, and you can look through them and check for the ingredients listed on the label.
Some do not include the black crystals which are a required ingredient for certain recipes. If you are uncertain, simply choose another brand.
You also want to check the sugar content and the number of preservatives and additives as well. Often you'll find that most labels don't list these ingredients, so check over them and get a feel for how much salt is in each brand.
Something else to consider is that while you can enjoy this type of truffle salt in any recipe, you may want to add a little more to enhance the flavor of some recipes. It's usually best to do this after the main flavors are added and to allow the salt to soak in.
It's even possible to cook this type of salt in the oven. If you bake in a traditional oven, you'll want to turn the temperature up to 350 degrees, which will enable the salts to absorb more of the flavors that you add to them.
In any case, black truffle salt is definitely a step in the right direction. The taste is robust and the flavorings are great for enhancing the taste of whatever dishes you decide to serve with this unique type of salt.
