I don't drink Milo like that. I mix it in hot water first, then chuck the milk in on top. If you just use milk, it won't dissolve completely. Not that that's a problem of course. It still tastes the same. BTW, for some reason there are still people who believe that Milo is meant to taste like chocolate. It isn't! It's a MALT extract, not a cocoa one, so it's not meant to taste like chocolate, unless you have chocolate that tastes malty.
