I've found a number of tutorials for making hot chocolate bombs if anyone wants me to post them. But they 1) use those artificial candy melt things that I don't think would be worth drinking or 2) require tempering chocolate which is do-able but majorly fussy for this time of year.
I just ordered mine from Costco.
In case it's a new concept, chocolate bombs are little chocolate spheres that fit in a cup and have cocoa powder and marshmallows inside. When you pour on hot milk, it melts the chocolate case and allows the contents to escape and create the hot chocolate. A little interactive fun for a cold, dark but nevertheless festive time of year.
