A friend of mine suggested I mix some instant coffee with some hot cocoa mix for a coffee mocha. Actually it tastes great, and a lot cheaper than Starbucks. However, the last two times I bought some coffee and cocoa mix I had a bit of a problem. I am not sure if it was the hot weather, but when I opened the vacume pack seal, there was a minor explosion. It was not a big deal, but it scattered quite a bit of coffee and the cocoa mix everywhere. Big mess. I bought some more yesterday, so to be on the safe side I took it out on the patio. Still a little explosion but not a big mess on the floor, just on me.
