Chill the Glass: Pop your glass in the freezer for a few minutes before making the drink for an extra-cold, frosty experience.

🔄 Hot to Cold: Turning Instant Coffee Into Iced Coffee

You might wonder: Can I just pour my hot instant coffee over ice?
The short answer: yes, but it’s better to dissolve the coffee first and then chill it down with cold water or milk before adding ice. This method prevents dilution and helps the drink maintain its flavor balance.

If you start with hot instant coffee:

Brew it strong (2 tsp instant coffee + ½ cup hot water).
Let it cool or refrigerate it for 10–15 minutes.
Add ice and milk or water before serving.

This approach still gives you that refreshing iced coffee taste without it becoming watery.
