Step 1

Place the ice into the bottom of a 4-cup (1 l) thermos flask, add the lime and mint, and fill with cold water.

Step 2

Fill your guampa about half-full of yerba mate.

Step 3

Place your palm over the mouth of the guampa, and give it a good shake. This will settle the plant material.

Step 4

Carefully tip the guampa diagonally, and remove your hand. The yerba mate will now have made a slope inside the guampa.

Step 5

Making sure not to disturb the yerba, carefully pour a little of the infused iced water from the flask down into the hollow, and let it stand for a few seconds to allow the yerba to absorb the liquid, which will help to not clog up the bombilla.

Step 6

Covering the mouthpiece with your thumb, place the bombilla into the space, and gently slide it just under the yerba at the bottom.

Step 7

Top up with more water, and sip the tereré. Refill as desired, until the yerba loses its flavor.
