Garlic powder is an excellent spice that should be kept on any spice rack. It can be an excellent replacement for fresh garlic. If you have ever cooked with garlic, then you know it is one of the most powerful flavors you can add to a dish, and garlic powder is much the same. It delivers a number of important nutrients, which provide various health benefits.
What is Garlic Powder?
Garlic powder is the ground form of dehydrated garlic and it has a number of benefits over fresh garlic. This powder is quite easy to make, and you will find it as a seasoning in various dishes like soups, stews, pizzas, salad dressings, and in sauces like barbecue sauce. 
Garlic powder can be a more subtle way of imbuing an entire dish with the flavor of garlic, rather than simply adding chopped or minced cloves. The versatility and delicious flavor of this powder make it a favorite spice around the world.
What’s more? When you dehydrate garlic, you extend its shelf life exponentially, so it can be stored for months or even years without losing its potency. It also delivers many of the best benefits of garlic in terms of health. Using this spice regularly can give your cooking and your overall wellness a boost.
