I signed up to take Yoonsun's Kimchi Making Experience with my daughter who wanted to learn how to make authentic kimchi. Yoonsun provides such a wonderful, personalized and unique experience that I feel honored to have learned her family's secret recipe. Yoonsun is such a great teacher and is really open about sharing her knowledge with others. She is very organized while making the class enjoyable. If you want to learn how to make authentic kimchi, you will not regret taking her class and if you feel you can learn for free from videos on the internet, it won't come out as good. Her techniques and ingredients (some are secret) are what makes it authentic...handed down from previous generations. I've bought many kimchi from stores and restaurants before and the kimchi we made tasted fresh because she advocates the use of fresh ingredients. She even cooked a very yummy meal so we can enjoy our newly made kimchi. I highly recommend taking classes with Yoonsun! The skill you learn and the recipe she shares is well worth the price.
