How simple. Hot water, two cubes (I like COFFEE!!), a little creamer. No waste, just stir till it disappears, and if you don't mix it all in, no big deal. The taste is great.

The black is the bomb

I have tried the vanilla and the mocha, even though flavored coffees are not my thing. I can drink them ok though, but the black coffee, I put 2 cubes in my cup (larger cup) fill with hot water, and that's it. Very rare can I NOT put additives and enjoy coffee, these are fantastic and BLACK is my all-time favorite. Passed out a few to friends at the last Amateur Radio Field Day, they wanted to know where I got them!! Yes, I gave them the URL.....

I love them!

I don't usually drink coffee at home, I leave it to the pros to make me my perfect cup, but with the health concers lately & lack of work options I've had to cut back & Clark's Cubes are an excellent alternative to my coffee shop addiction!
