Brew Mate with an Espresso Machine
1. Thoroughly clean your espresso machine’s portofilter to remove coffee oils.
2. Pour 2 tablespoons of loose yerba mate into a small cup.
3. Add enough cool water to make a loose "paste."
4. Spoon this yerba mate "paste" into the espresso machine's portofilter and pack it in lightly.
5. Make a shot of green espresso for use in "mate lattes," "green granitas," etc.
