I was sent the Make Your Own Chocolate Kit to try out and review here on the blog. It's a fun little kit that makes a good amount of chocolate and comes with everything you need, including written instructions that include some interesting information about chocolate.
Basically you heat up some cocoa butter, add your cocoa and sugar and wait until it comes down to the correct temperature (tempering!) before adding the seed chocolate. They even include a little stick on thermometer to attach to the bowl, so you don't even need to worry about that.
We added some goodies to the bottom of each of the provided candy cups, poured in the chocolate and thew it in the fridge for a few minutes to set up.
This was a fun project which I did with my 12 year old. We both had fun, learned a little something and enjoyed the chocolate. I'd recommend this to anyone with kids who are looking to explore a little food science.
