I have the following at hand: 4 oz. cold coffee 4 oz. hot coffee 16 oz. glass Plenty of ice My objective is to combine the hot coffee, the cold coffee, and the ice so I end up with the least-diluted coffee after it sits for a minute or so. In what order do I add the ingredients for best results? Or doesn’t it matter. Note: Glass breakage due to heat/cold variance is not an issue.
