If your idea of ??iced coffee is “let it cool”, oh let me tell you, you deserve more than that. Iced coffee has a specific process, so if you want to enjoy it during these as the temperatures rise, follow the steps below.
First, fill the cup/glass with ice and make sure you have a spoon as long as the cup/glass so you can stir it better.
Second, throw in the pre-made coffee. Care must be taken here as the coffee should be as warm as room temperature. So it should NOT be hot.
Third, add the milk. The amount of milk in the glass can also be seen from the color that the coffee starts and takes. If you like it with a lot of milk, wait until the color is neutralized.
Fourth, skip the sugar – if you prefer it sweet. You can also add other sweeteners. Some prefer caramel.
Finally, stir.
