In the Mexican tradition, the Sangrita cocktail is drunk with a shot of tequila. The sangrita exists prepared in a bottle.
The recipe sometimes includes chilli and onion, in which case the ideal is to make several sangritas at the same time and put them in a blender. Add 1 small onion and 1 small red pepper for about 6 sangritas.
By mixing tequila with sangrita you get the Vampiro cocktail.
