Make sure you salt Brussels sprouts at the beginning of the cooking process. And then go in with a good pinch of sea salt or kosher salt before serving.
Sweet flavors to put with sprouts are apples, dried cranberries, apple juice/cider, sweet white wine, basil, flat leaf parsley, sugar, brown sugar maple syrup and molasses.
To cut through the strong flavor of Brussels sprouts try adding lemon juice, a tangy Dijon mustard, a splash of dry white wine, cider vinegar or a drizzle of your favorite salad dressing.
