Here's a refreshing coffee treat you can whip up in no time. Start with 150 grams of ice, add 12 grams of your favorite instant coffee, and sweeten it with 85 grams of either white or brown sugar. Pour in 100 milliliters of cold water, and for an extra touch, sprinkle some cacao powder if you like. A special thanks to goldenbrown.coffee for this delightful recipe.
