Some ghees are light, whereas others are thicker. If you want to know what is the best way to buy ghee from online stores, you must first determine which qualities you're looking for.
Ghee's composition depends on its ingredients. If you were to buy the only regular ghee for cooking, you would not be able to tell what is the best ghee to buy because plain ghee does not have any distinct qualities that would give you an idea of what is the best.
For example, if you buy plain desi ghee, what you'll really notice is that apart from being a thin consistency with a very clear and rich taste, this type of ghee has no odor or taste and is highly clarified.
So, if you are searching for what is the best ghee to buy, all you need to do is look out for organic ghee that has a high percentage of monounsaturated fatty acids.
Monounsaturated fatty acids are great sources of vitamin A, D, and E and a variety of other nutrients, as well as being the key element for the production of a natural emulsifier called "fat-soluble vitamins".
