I believe there is a very traditional kimchi and there are many many differing versions using different veggies and base flavorings. We make tons of kimchi and nearly every batch is different depending on the vegetables and spices we have on hand. We don't go out to purchase specific ingredients, but are excited for the next unique outcome. The process is basically the same, however, so we enjoy shaking it up and experimenting with variations of all kinds.

Thanks for the comment @gooddream!
