* The recipe was originally written using all apple cider vinegar. But then I tried using a mixture of apple cider and red wine vinegar, and now there’s no going back. They taste so much better when you combine these two. But feel free to use all apple cider vinegar (or all red wine vinegar) if that is all you’ve got. They will still be delicious.
