My grandchildren always ask for hot cocoa at my house. I think my homemade hot cocoa deserves real whipped cream to top it off, but that was a pain for a small amount on top of cocoa. So, I tried the canister. I just put a little heavy cream in, screw on the lid, pop in a cream charger and press to discharge into the cream canister and instant whipped cream. It is perfect for the job.
