Heirloom Recipe from The Belgian Cookbook 1915
(A very interesting recipe!)
Shred some red cabbage, to half a pound of it add two medium sized apples, minced finely without core or skin, a bit of fat bacon, season with pepper, salt, vinegar, which should be tarragon vinegar, and put it to simmer in some gravy or milk and water. It should cook for an hour over a gentle fire. Cook separately some green cabbage, cleaned, boiled till tender in salted water, chopped, then put back on a gentle fire with salt, pepper, a dust of nutmeg, and some fat or butter. Let it heat and mix well, and then serve the two colors side by side in the same dish; the red cabbage has a sour and the green has a nutty flavor which is very agreeable.
