Preparation

   Pour the tequila, then the champagne, into a short glass without ice, leaving about a fifth of the glass empty.

2. 02

   Stir very gently so as not to knock out the bubbles.

3. 03

   Cover the glass with the palm of your hand and slam it down sharply on a hard surface.

4. 04

   Drink it immediately in one go, before the foam overflows.
