Whipped cream fortified with grain alcohol -- Sarah found entertainment for your snow day at the Owen Brown Liquor & Spirits in Columbia.
Sarah blogs about "Whipped Lightening" and using it to top hot chocolate. I assume this is available elsewhere.
Remember to check the bottles carefully. Liquor stores sometimes try to pass off Whipped Lightening as the legendary 2005 vintage. That hot dry summer in Provence brought out magical fruity notes in the alcoholic whipped cream. It hasn't happened since, so don't pay top dollar for standard "whipanol."
