A dark, smoky, and tart Halloween cocktail featuring blackberries, mezcal or bourbon, and a black salt rim, designed to look like a bubbling cauldron with optional smoke effects.
Use fresh-squeezed lemon juice for the best flavor. If using frozen blackberries, let them thaw slightly. For a non-alcoholic version, substitute the spirit with blackberry juice or grape juice. The drink is best served immediately to maintain the smoke effect and temperature.
