Mix the cabbage, bell pepper, onion, and radishes with the salt and place in a strainer set over a bowl. Refrigerate overnight.
Press out as much liquid as possible from the vegetables.
Combine the vinegar, honey, mustard, turmeric, horseradish, cloves, bay leaf and chili with 1/2 cup water in a large pot and boil for 5 minutes. Add the vegetable mixture, toss to coat and bring it back to a boil. Remove from the heat and let cool to room temperature. Transfer to a container and store in the refrigerator for up to 7 days.
