How to make a delicious cold coffee from ground coffee? I am new to coffee drinking and I just checked what I am drinking till now is instant coffee. So, I was wondering is it possible to make cold coffee? Not cold brew, just a normal cold coffee with ground coffee? And, how to make it an amazing one?
What you have mentioning is widely known as iced-coffee.

The most widely adopted method is to brew any type of coffee: filter, drip or french-press. Then, adding ice cubes in a cup and pour the coffee to fill the cup. After that, you mix it to homogenize the temperature, add milk and sugar if desired.

Another method is known as Japanese brew. In that method, you prepare an ice cube filled cup beforehand. Then, pull your shot of espresso on top of ice. (Optionally, filter/drip on top of ice.) This method is known to preserve aromas better than the previous.
