This Freezer Cabbage recipe offers a tangy, crunchy slaw that keeps beautifully in the freezer, making it a smart make-ahead side dish. Combining shredded cabbage and carrot with a sweet-and-sour vinegar syrup, this method was popular in mid-century kitchens as a way to preserve seasonal produce without canning. The result is a lightly pickled slaw perfect for topping sandwiches or serving as a refreshing side. Its crisp texture and zesty flavor make it a nostalgic favorite for potlucks, picnics, and family dinners.
