I have some recent experience with soup in appetizer form. When our esteemed co-founder Sarah threw me a wedding shower, one of my bridesmaids, Stacey, made tomato soup. We served it in tiny votive holders – essentially, a shot glass of soup. That mimicked one of the appetizers we would serve at our wedding, with a mini grilled cheese sandwich added as a grand embellishment. A brie and caramelized onion grilled cheese, nonetheless.
I won’t delve too deeply here into the presentation bit, as I have it on good authority that you’ll see a mini food month from WTE in 2014. I’ll just say this: Any of the soups here would be great in whatever mini form you choose.
