Black truffles are a fungal genus of microscopic fungi, which are present on land as well as in the water environment. The name black comes from their melanin pigments that give them their color. A black truffle has a silvery grey appearance, with its white tips having an even texture.
Black truffle is actually the fruiting body of an ascomycetous subterranean ascomycete fungus, mainly one of four species of the same genus Tuber which live underground. Apart from Tuber, several other genera of subterranean fungi are also called black truffles including Geoporus, Peziza, Fichus, and a few more. As their name suggests, they can be found in the dark places of the caves and underground where most fungi thrive. The fungi responsible for this distinctive feature of black truffles come in different shapes and sizes, but they are all microscopic.
When a black truffle starts growing its spores are very fragile and can easily be broken or crushed. It can also be released into the air after being harvested, though it can still be picked up by hand. Once it is picked, a good way of preserving the product is to freeze it. Black truffles, however, will last longer when kept at room temperature.
Because they are so fragile, black truffle sea salt should be used as much as possible during the winter months, especially at the beginning of the season. They tend to produce more black dust than any other food and some of the dust is really toxic. They are also very sensitive to salt vapour, so it would not be a good idea to leave them out in the open or use a high powered hairdryer on them. If you do not have a refrigerator or a freezer in your cellar, you can always store them in a plastic bag in a cool dark place or in your own pantry.
The black truffles' succulence comes from the fact that it contains a number of flavonoids, a group of chemicals, which are responsible for its flavour. They are also responsible for the dark colour of this salt. Other varieties of fungi contain only flavonoids which provide a yellow tint in them, such as those from the Aspergillus genus are usually blue in colour.
Because they are quite fragile, black truffle salt can be easily broken or crushed to extract the black dust. This dust can then be used to make truffle salt or any other recipe for making truffles. There are many recipes available for making this salt and some people have claimed to use it as an alternative to olive oil.
Truffles are highly nutritious food and have been known to contain significant amounts of potassium, magnesium, iron, vitamin E, folate, manganese, thiamine, niacin, riboflavin, phosphorus, copper, potassium, calcium, selenium, copper and sodium. They are also known to help in lowering blood pressure and to fight against various cancers. Black truffle salt has been found to have antibiotic and antifungal properties.
Truffles are commonly found in France, Italy, Switzerland, and the Rhone in particular, but have been eaten in many countries throughout the world. It has become popular as a sweet treat in North America, though they are also consumed as a part of desserts. In most parts of the world, the only way to obtain black truffles is to buy them from an online retailer who may be able to get them at a discount from the production plant that produces the product.
To prepare truffle salt for consumption, one has to melt the black truffle. Then, when the mixture cools down, it should be filtered out. Some of the salt will stay in the crystals but it will easily dissolve when cooled further after it is filtered.
For some people, the salt tends to have a salty taste, and the flavours become enhanced by being cooked. This may give the salt a bitter or metallic taste. This problem can be overcome by using a food processor that is designed for this purpose and using a high powered hair dryer to heat the salt crystals until they are about sixty degrees Celsius.
When buying or preparing the salt, you will probably find that it is more expensive than ordinary salt. However, once you get used to it, you might not need as much of it and will not notice the extra expense.
