Fill the cup (Gourd) two-thirds full with Yerba Maté. Cover the opening with your hand, turn the cup upside down, and shake gently to let the fine powder settle in your palm. This prevents clogging the Bombilla.
Hold the cup at a tilt (approx. 45 degrees).
Pour a little lukewarm (not hot) water into the lower part of the tilted cup to moisten and set the yerba at the bottom.
Insert the Bombilla into this moistened section and press it against the wall of the cup. Do not move it after this point. You can set the cup upright.
Heat the water to a temperature of 70–80 °C (158–176 °F). Never use boiling water, as it will burn the leaves and make the drink bitter.
The Cebador (the person preparing) pours hot water into the empty section of the yerba (where the Bombilla is located). The water should only fill a portion of the yerba.
The Cebador drinks the first, strongest pour. Then they hand the Gourd to the next person in the circle. Everyone drinks until the cup is empty and returns it to the Cebador for refilling. The ritual continues until the yerba is 'washed out' (lavada).
