I made cold coffee at home and it turned out really watery and bland.
I mixed 1 tbsp instant coffee with 1 tbsp cocoa powder and 2 tbsp hot water. Then after the mixture came to room temperature, i put the mixture in a blender along with 1 cup of cold milk and 2 tbsp sugar, and blended. I didn't put any ice.
The resulting drink was watery and while it wasn't extremely bad, it wasn't good either.
What should i do, to make it less watery and make it thicker? It tasted more like coffee flavored milk than cold coffee :( What am i doing wrong?
