With one of my coworkers planning a wedding, a hot topic in the Test Kitchen has been catering companies and all the add-ons they offer. There's the ubiquitous chocolate fountain (which has grossed me out since I learned that it takes gallons of oil to keep it flowing properly) and the late-night coffee bar. My colleague Kate Heddings has not stopped talking about the mashed-potato bar she encountered at one wedding, with toppings ranging from chili to caviar. The latest add-on in Austin? Snow cones. But instead of flavoring the shaved ice Snoopy-style, with artificially colored, faux-fruit-flavored syrups, local event-planning company Caplan Miller uses liqueurs like Kahlúa and Baileys Irish Cream.
