This recipe came from The Gluten Free Kitchen. I've been making it off and on for years. The original headnote describes them well: "These are mild, thick pancakes, fashioned after the buttermilk pancakes made from mixes that are found in the grocery store baking aisle. They are great served with butter and syrup." Since they are made with starches and no whole grain flours, they are very light - similar to white flour as compared to whole wheat. This is also handy for people just getting started with gluten free cooking or wheat eaters who want to cook for a gluten intolerant relative/friend but only have access to common grocery store ingredients (the xanthan gum isn't essential but does improve the texture). If no buttermilk on hand, substitute 3/4 cup milk and 3/4 tsp vinegar.
