Mystery Ingredient: Sweet Osmanthus (gui hua 桂花)

Growing up with Chinese cooking in the home, there were a lot of unique ingredients that I had the pleasure of experiencing, often without even knowing how special they were. It wasn’t until I moved out of the house and started cooking out of my own pantry that I suddenly realized just how interesting some of these Asian ingredients were (and how hard they can be to obtain!). I sometimes start to worry that I might go stir crazy if I move to a place without an Asian market, because I’m pretty sure I wouldn’t be able to cook half the things I cook without one! It is my hope that through my posts I can introduce some of these interesting ingredients to all of you, and maybe the next time you wander into an Asian market, you won’t feel as intimidated by your surroundings. Maybe you’ll even experiment with a thing or two!

Enough about me, let’s talk about today’s mystery Asian ingredient – sweet osmanthus. If that name sounds completely foreign to you, don’t worry. I had to look it up just for this post! In fact, growing up, the sweet osmanthus was always called by its Mandarin name in my household: “gui hua” (桂花). It sounds something like “gway hwa”. It is the fragrant dried small yellow flowers of the sweet osmanthus tree that we value in cooking. These trees are found in Asia, particularly in eastern and southern China. And if you ever have the pleasure of visiting when they are in bloom in the fall, the fragrant flowers will woo you with the scent of apricots. The flowers can be white, yellow, or even orange. The dried flowers are tiny, about the size of rice kernels, and retain their sweet fragrance.

It is this sweetness that makes the sweet osmanthus so popular in Asian cooking, particularly in the desserts. In fact, you can buy the sweet osmanthus as unsweetened dried flowers, as a jam paste, or even as an infused sugar (much like vanilla sugar). When I was younger, my mother would often prepare one of my favorite desserts, lotus root powder congee with sweet osmanthus. I know, that’s a mouthful, and you probably also have no idea what this lotus root powder congee is. Perhaps that should be its own mystery Asian ingredient post sometime! Suffice to say that it’s a thick starchy soup made from ground lotus root and flavored with sweet osmanthus sugar. It was always warm and soothing to eat… a welcome treat in the wintertime or at night. And it was never quite complete without the sweet osmanthus sugar, although it’s hard to put your finger on exactly how the flavor changes. But you just know, when it’s not there, you’re not getting the whole package. As I grew up, I began to learn that the unsweetened sweet osmanthus flowers are often infused in teas in China. Green teas and black teas, they would only need a sprinkle of sweet osmanthus before steeping with hot water, and the fragrance would bloom. What a wonderful little flower!

As it turns out, what with this tree being native to Asia and all, sweet osmanthus is pretty difficult to obtain in the US. I sort of think of it as the saffron of China. Whenever I see it in the Asian markets, sold as jam or sugar, it is at a premium price (something like $4 for a 1 oz. jar). If you are looking for it, you can sometimes find it under the name “cassia flower”, which is a literal translation of the word gui hua, but not the proper name for the flower since cassia is a different species. I have also heard that the sweet osmanthus is known as the Tea Olive down south in the US. In any case, my source of dried sweet osmanthus is typically straight from China. When I go to visit my relatives in Shanghai, they give me a baggie of the stuff, and it lasts a long time. I love infusing my tea with it, and sprinkling it into some of my desserts for a sweet fruity aroma and flavor.

This week I was making a coconut sago dessert soup at home, enjoying the lovely scent of the coconut milk as I was dissolving rock sugar into it, when I had the idea to toss in some sweet osmanthus. It was a wonderful combination! I have previously posted my taro sago with coconut milk recipe, but the one I made this week was slightly different because I did not have any taro and only had 1 can of coconut milk. The soup was  very thin (not thickened like the taro sago), but at the same time very refreshing with the nice chew from the tapioca. Some restaurants like to serve it thinned and some serve it thicker. I like both versions, depending on my mood! The sweet osmanthus definitely added a delicately sweet aroma and a little bit of that “je ne sais quoi” to the coconut milk, and thus I was inspired to write this post. While I was doing some reading on the Wikipedia article, I noticed that the sweet osmanthus supposedly has neuroprotective, free-radical scavenging, and anti-oxidant properties! A superfood of sorts! In any case, I hope you’ll find the opportunity to try it sometime, or I hope at least it was interesting to hear about :)

Coconut Sago Dessert Soup with Gui Hua (Sweet Osmanthus) (makes 8 servings)

Recipe adapted from Taro and (Tapioca) Sago in Coconut Milk

Ingredients:

  • 1/2 cup dry mini tapioca
  • 1/3 cup rock sugar (or granulated sugar)
  • 1 can (14 oz.) coconut milk
  • 3 cups milk
  • generous sprinkle of dried gui hua (sweet osmanthus)

Directions:

1. Bring a pot of water to boil, and add the dry mini tapioca. Boil for 6 minutes, then turn off heat and cover, allowing the pot to sit for 15-20 minutes, until the centers of the tapioca are translucent. If they remain opaque in the centers, you may heat up the pot while stirring, until the tapioca are translucent.

2. Meanwhile, in a large pot, add the coconut milk and rock sugar, and heat on medium to medium-low. Continually stir the rock sugar until it dissolves completely. Do not let the coconut milk come to a full boil (it may curdle). Sprinkle the sweet osmanthus into the pot when the rock sugar is nearly dissolved, allowing it to heat with the coconut milk for about 5 minutes.

3. After the rock sugar dissolves, turn off heat and stir in the milk. Taste for sweetness at this point, and adjust as necessary by adding granulated sugar or more milk as desired. It should be slightly more sweet than your final desired sweetness.

4. When the tapioca is ready, pour it into a fine sieve while running cold water over it to wash off the excess starch. Add the tapioca to the pot with the milk, and stir well to break up the tapioca clumps. Serve warm, at room temperature, or chilled, as desired. (The coconut milk may clump slightly when chilled.) Sprinkle more sweet osmanthus on top for garnish when serving. Enjoy!

    So I’m hoping you can accomplish what I cannot. Perhaps your relatives know of a vendor willing to ship to the US? I have been looking for osmanthus blossoms for more than a year and even the alleged king of herbs and spices in NYC who has a “we can get anything” promise has ignored three of my emails. I guess they’d rather keep a record than a promise. Thanks in advance!

      Hi Ann,
      You can get sweet osmanthus jam in Asian markets pretty readily, but if you want the dried flowers, my best suggestion to you is to find someone who will be traveling to China or has contacts coming to the US from China. It is very easy and cheap to get dried sweet osmanthus in China and have someone bring you a bag of it in their suitcase. I brought back a ziplock baggie’s worth during a trip to China and it has lasted me several years. So if you have any friends or acquaintances that are Chinese, ask around if they have relatives coming or if they are traveling back anytime soon. In the Chinese community, we always obtain our favorite Chinese ingredients this way through friends and relatives!

    I have this plant growing in my yard! Io e the sweet blossoms!!!! I can’t wait to try all your suggestions. Do you have any tips on drying the flowers yourself, or should I use them fresh?

    • Lucy

      I’ve never tried drying fresh flowers myself, but it certainly sounds like it’s worth trying! How nice that you have some growing in your yard :)
