YouTube video illustrating problem.
Someone (Facebook video) suggests using a food processor but I don't have a food processor. (Also, her Milo doesn't seem to be nearly as hardened as mine or in the above YouTube video, where a knife is more likely to break before making much progress.)
One page claims:
How to soften hardened Milo powder
One proven method is to take the milo out of the tin and place it in a Ziplock bag, the with a meat cleaver or rolling pin beat the milo until it turns into powder again.
I've tried repeatedly smashing my big lump of Milo powder with a 7.5 kg dumbbell. But after a few minutes, all that's happened is that the big lump has broken into several smaller lumps, with no sign that the Milo will ever turn back into powder. (Meanwhile the layers of bags that I've enclosed my Milo in have been torn and must be replaced.)
Perhaps with a few hours more smashing, it'll eventually turn back into powder. But does anyone have a better solution?
(I'm also using the Gao Kosong formula which is perhaps especially susceptible to this problem.)
