Caramelized onions make these delicious biscuits slightly sweet and moist, and they are wonderful with a variety of spreads. Use an herb butter, a cream cheese spread, or your favorite chutney or hot pepper jelly on the biscuits, or use them as sandwiches with slices of roast beef, ham, or chicken. Use a small biscuit cutter to make mini biscuits. The onion flavor makes the biscuits them an excellent base for mini pulled pork or roast beef appetizer sandwiches. It's an easy, basic biscuit recipe, and you can cook the onions a day in advance. Refrigerate them and make the biscuits the next day.
