I’m trying to make 8-hour old coffee palatable by adding both chai tea and hot chocolate mix. It’s…palatable.
The Coffee Bean and Tea Leaf has a drink they call a Moroccan Mint Latte. It’s a tea latte with chocolate. You can get a fairly good approximation by making hot chocolate using mint tea instead of hot water. Katie suggested Bigelow Plantation Mint (after I mentioned that I’d tried it with Stash Moroccan Mint), which seems to work well.
Update: I forgot to mention the key difference between the two varieties of tea that I tried. Black tea works better with chocolate than green tea.
