Cold coffee has a specific process so if you want to enjoy it during these hot days, follow the steps below. If your idea of ??cold coffee is "let it cool", oh let me tell you, you deserve more than that, good people.
1. Fill the cup / glass with ice and make sure you have a spoon as long as the cup / cup in order to stir it better.
2. Pour the previously prepared coffee. Care should be taken here as the coffee should be as warm as room temperature. So it should NOT be hot.
3. Add the milk. The amount of milk in the glass is also evident from the color that the coffee starts and takes on. If you love it with a lot of milk, wait until the color is neutralized.
4. Add sugar - if you prefer sweet.
5. Finally, stir.
