Braised red cabbage with apple cider and currant jelly is a classic sweet-and-sour side dish that pairs beautifully with roast pork, sausages, chicken, and classic holiday entrées.
Quarter the cabbage lengthwise and trim away the core from each section. Thinly slice the cabbage and transfer it to a heavy soup pot or Dutch oven.
Add the salt, butter, and apple cider. Cook over medium-high heat, stirring occasionally, until the cabbage softens and begins to wilt, about 10 minutes.
Reduce the heat to medium and stir in the currant jelly until melted and evenly distributed.
Cover the pot and continue cooking, stirring every 5 minutes or so, until the liquid has reduced and the cabbage is tender and lightly glazed, 25 to 30 minutes longer.
Taste and adjust the seasoning if needed, then transfer to a serving dish and serve warm.
