"Seasoned" rice vinegar is sweetened rice vinegar. The difference is sugar, and "seasoned" rv will make your garlic cloves like candy! Crisp. crunchy garlic candy...yum! One of my clients, John Iwata, the premier landscape gardener of Ojai, gave me some sweet garlic pickles about ten years ago, and I've been making them ever since. His wife, Sally, and I swap recipes (and kimchi) occasionally.
