Yesterday Marco and I made two sorts of ice cubes:
On the top you have coffee ice cubes (just make coffee and let it cool, then put it in the freezer). The other is chocolate and agave syrup ice cubes (1/4 cup agave syrup, 1/4 cup cocoa powder, and two cups water — receipe taken from here).
And no, I have no idea why the middle three ice cubes are lighter in color. Weird!
Above: the chocolate/agave ice cubes.
Above: The finished product. Yum. I can think of some ways to improve it (and add texture) but for a first try it was pretty good.
