Caraway seeds, onion, and ale transform the humble condiment of jarred sauerkraut into a stellar side dish. It's good on a bun with a beer-cooked sausage or simply on its own, by the forkful. Prep and Cook Time: 45 minutes. Notes: Keeps up to 2 days, covered and chilled. Bring to room temperature or warm gently before serving. We found that most brands of sauerkraut had plenty of flavor without additional salt, but be sure to taste the finished dish and add salt if you like.
