Your friends were talking after your last dinner party, and it wasn’t good. Maybe it was the lint-stuffed mushrooms. Perhaps it was the Clamato smoothies. Either way, you need to step up your game before you invite anyone else over, and the Emsa Flow Carafe ($45) is a good start. The innovative freezable cooling coaster and stainless steel pouring spout makes it perfect for serving up wine, cold water, lemonade, tea, and… sure, OK, and Clamato.
