Gâteau du Soleil Owner
Jihyun Seo,
Hi, my name is Jihyun Seo. I am a pastry chef specializing in Asian desserts and run Gâteau du Soleil, a wagashi shop, and Kashikoi, a cafe. After teaching English for ten years, I felt the desire to live a more exciting life and opened a studio on a whim in 2017, where I held classes on making bean paste flowers, craft jeolpyeon, and flower songpyeon. I then went to Japan to learn skills from a third-generation wagashi master, which made me who I am now.
Since I didn't formally study baking, I had to go through so many trials and errors, which allowed me to become an instructor who understands how beginners feel. Since starting my business, I have taught more than 5,000 people in my wagashi classes. Drawing upon such know-how, I'd like to help learners on Coloso understand wagashi even without a related degree.

Asian Dessert Expert,
Jihyun Seo

Student Reviews
Class Recommended By Jihyun Seo's Students

Owner of a wagashi shop in Incheon @gom****Although I loved so many things about this class, the best part of it was that you can experience the entire process of learning on your own. While most classes provide basic recipes, the instructors usually have some work, such as coloring, finished in advance to save time. As a result, even though you think you've understood everything at first, you soon realize that you actually haven't. In this class, however, I could experience everything that significantly affects the product in practice, such as time, concentration, stickiness, and color. As someone new to this industry, I learned so much from Jihyun's class, and I strongly recommend it to everyone!

Prospective dessert shop owner in Seoul @lif******Although the students all came from different parts of the country and the world and with varying levels of skills, Ms. Seo quickly noticed such differences and took great care to ensure that everyone could learn with ease, which I found very impressive. It's okay even if your pace is quite slow, because she teaches everything in such detail. She helped me finish every process on my own, without skipping any part, so it was very easy to review what I learned. Thanks to her, I can now make wagashi as gifts for my friends or as a special dessert for traditional holidays. I can't wait to see what her next class will be like.

Wagashi class instructor in Seoul @wol*****I took Ms. Seo's class last winter and opened my shop just three months after that. I have run it successfully for already a year now. At first, I didn't even know how to create colors, but now I can combine colors on my own and enjoy making wagashi so much that it's like I'm living a new life every day. I will forever be grateful to Ms. Seo, who introduced me to the delightful world of wagashi.
