This comes from "Jo Sealard's New Zealand Country Cooking.". I haven't made it yet. I think instant coffee powder must be something different from the instant coffee we use with hot water to make the beverage because she says nothing about heating up the milk first. US instant coffee granules wouldn't dissolve w/o heating the milk. Therefore, anyone making this needs to find the powder itself or heat the milk somewhat and then let it cool back down so that it doesn't cook other ingredients (I would think).
