Infuse vodka at least 24 hours ahead for best flavor. You can swap vodka for rum or tequila, or use sparkling water for fizz. Store infused vodka in the fridge up to 1 week. Freeze leftovers in an airtight container and blend before serving. Serve layered slushies immediately to keep distinct colors.
