燒仙草: Hot Grass Jelly
cooking with steam season two, episode five, with Jess Wang of Gu Grocery

The second season of our Taiwanese cooking show, Cooking With Steam, explores Taiwanese food through the lens of 古早味 gu zao wei. This phrase translates to “ancient flavor,” but largely refers to pre-war Taiwanese foods that feel especially homestyle to me.
The final episode of Cooking With Steam’s second season is out! I team up with my friend and collaborator Jess Wang of LA’s Gu Grocery to bring you Hot Grass Jelly and Tang Yuan 燒仙草, one of my favorite Taiwanese desserts, and perfect for the winter weather.
Lantern Festival, falling on the 15th day of the first lunar month (March 3rd this year), marks the end of the Lunar New Year Spring Festival period. During this time, it’s customary to make a tang yuan dessert to enjoy with your loved ones—the roundness of tang yuan 湯圓 and the yuan 圓 in its name symbolize togetherness and unity.
In this episode, Jess and I make tang yuan as a topping for hot grass jelly, a thickened pudding made with grass jelly herb. I’d enthusiastically describe this as the opposite of ice cream: warm, heady, and full of sweet herbal notes. The toppings add texture of all kinds, from the crunchy, toasted walnut to the chewy, sweet bite of the tang yuan.
I always say that one of my favorite things about Taiwanese traditional desserts is the N U T R I T I O N. This one is made from beans, walnuts, rice, spirulina, and herbal tea, with a little bit of rock sugar.
The secret to making tang yuan, learned from Jess, is going by feel. You’ll see in the episode how we judge the dough (with cheese analogs?), and add water or rice flour as needed. As seen below:

Meet Jess Wang
Jess Wang is an artist, pastry chef, and fermentation educator based in Los Angeles.
After a decade of experience in restaurant and catering kitchens, she started Gu Grocery, a Chinese Taiwanese grocery that’s been operating in the form of pop-ups and workshops in LA for several years. She collaborates with her Taiwanese-born Wenzhounese mama, Peggy, to preserve old family recipes and develop new ways of making food. She’s about to take Gu to the next level with the opening of a brick and mortar grocery and deli in LA’s Chinatown.
I’ve learned so much from her over the course of our friendship, not just about Taiwanese food, but also how to thoughtfully engage in community and family while inviting people into traditional foodways. For example, while preparing her grocery to open, she’s been teaching tang yuan making classes throughout the Los Angeles Public Library system. We’re so happy that she was able to make an appearance on the show, amidst all she has going on, and so grateful for her time and knowledge (and also the hardboiled egg she peeled for me on set).
In her words:
Gu Grocery is a dream come true Chinese Taiwanese online store offering high quality pantry staples and a collection of everyday home goods. We regularly pop-up around LA to serve a bakery deli menu of sorts, featuring nostalgic snacks, some surprises, and familiar comfort foods to nourish you.
Our long term goal is to open a shop where we can continue serving our loyal pop-up customers while also meeting the needs of the diverse residents of the Chinatown community. Located in the heart of Chinatown, our future brick and mortar store will accept EBT and offer senior discounts.
You may be wondering what Gu means? Gu stems from the Chinese character for mushroom that is traditionally a symbol of prosperity and fertility. In Mandarin, it is also the word for Aunty, which honors the strength and generosity of women who have filled the role of intergenerational caretakers in our families 🍄
Inspired by our fungi friends and their crazy mycelium network - we believe in the power of a community and see ourselves as just a few among many spores in supporting you on your food journey. Whether it’s creating access to healthy food options or providing opportunities to learn about fermenting, cooking together is a wonderful healant. We invite you to join us in the heart of the Gu kitchen.
So much of this is inspired by and informed by Jess’s mother, Mama Peggy, whom we also adore. She came to Frankie Gaw’s First Generation Book Opening party (hosted at Yun Hai) and spent the whole evening celebrating with us (and went and got pizza for everyone too). Her generosity says it all.
If you’re ever in LA, don’t miss your chance to experience Gu Grocery at one of their many pop ups or their forthcoming space in Chinatown.
The Recipes
Hot grass jelly is really easy to make! The tang yuan are a cinch, too, once you’ve got a sense of how the dough should feel. Once you’ve got the basics down, it’s fun to play with colors (dragonfruit juice!) and fillings (black sesame!).
I love making a big batch of tang yuan all at once and freezing them. You can freeze them directly after rolling, and cook them from frozen too. Just separate them on a baking sheet or platter, and par-freeze them for an hour or two before transferring them to a container or plastic bag for long-term storage, to prevent sticking.
I prepare the grass jelly tea in a Tatung Electric Steamer, but you can also do it in a stockpot on the stove. The full recipes are posted on our site. Get the recipes or the grass jelly herb below:
Ingredients and Equipment
I love to show off my collection of ceramics, props, everyday objects, and kitchen tools on the show, many of them gifted by friends or collected personally over the years. Here’s a little more information on what I used this episode.
The HeySong 黑松 glass is a vintage piece I found while shopping in Taiwan.
The blue and brown bowls for holding the toppings and serving the final dessert were made by my friend and ceramicist Matthew So. The green colander for holding the non-dairy creamer is from a little hardware store I walked past years ago in Taiwan.
I brew the grass jelly tea in the 11-cup Tatung Steamer.
And, we used grass jelly herb that we import ourselves as the foundation of this dessert.
Please reach out with any other questions on sourcing or ingredients. Happy to help, as always.
Gratitude and Acknowledgements
