Coffee
"Instant coffee" is a very quick way to make a cup of coffee to drink. It is made in a factory and sold in jars or packets. First, strong coffee is made using ground coffee and boiling water. Then, the coffee grounds are filtered out. The coffee liquid is dried out until nothing is left except granules (little crunchy pieces), or fine powder. This is then put into jars or packets. As soon as a spoonful of "instant coffee" is added to boiling water, it dissolves in the water to make coffee to drink.  The taste can be very different from fresh coffee. Part of the reason for the different taste is that Robusta coffee beans are usually used for making instant coffee. Robusta coffee beans do not cost as much as Arabica.
