It always annoyed me that whenever I made hot cocoa (from a packet) there would be lumps of the mix all over my drink and I would take a sip and the lumps would break in my mouth spreading this concentrate of hot cocoa all around. I didn't like it.
Well, I figured out a way to stir my hot cocoa and get the lumps out. I use a fork instead of a spoon or plastic/wooden stirrer. And guess what? My hot cocoa has always been nice and smooth since I figured out this little secret. Maybe I'll invent a hot cocoa stirrer (if they don't already have one).
