Grass Jelly Milk Tea with Sea Salt Cream Top (Tra Sua Suong Sao)

I once told my husband, "If you cut me open, I'll bleed milk tea." He asked, "Why are you so morbid?" I don't know. At the time, it was the only way to accurately express my love for milk tea. What can I say? The love is real and strong.

Lately, I have a thing for grass jelly in my milk tea. Milk tea and grass jelly with a cream top and a sprinkle of sea salt? Oh God. Yes, please!

Grass Jelly Milk Tea with Sea Salt Cream Top (Tra Sua Suong Sao)

You are probably wondering what is grass jelly?

Grass jelly, or Sương Sáo, is a black gelatin that begins with boiling the leaves and stalks of the Chinese Mesona plant, a mint family member. The deep dark black tea is then filtered and a bit of starch is added to gelatinize. Once the mixture is cooled, it is cut into cubes and used in many desserts and drinks in China, Hong Kong, Taiwan and Southeast Asia. Grass jelly is served as the one of the many toppings in Bubble Tea/Boba shops. Having a cold sweet drink with grass jelly is a great way to cool yourself off during the hot Summer days.

Grass jelly has many health benefits. It relieves digestive problems. It cures cancer, diabetes, mental illness, and it gives you wings. Its flavor is earthy with a slightly bitter and herbal undertone. For us silly Asians, this makes it a perfect contrasting component in desserts and drinks.

Here in the States, grass jelly is found in canned or powdered form. The canned form is already made. The jelly slides out like canned cranberry sauce. Simply dice it up and add it straight to the dessert or drink. The powder form is for those who want to make it fresh or for those who want to adjust the sweetness. The package comes with grass jelly powder, sugar and gelatin. Heat up the powder with water, add the sugar and gelatin, and allow it to set before use.

When I return to Vietnam in the near future, I would like to hike the hillside of the Vietnam countryside, pick and dry my own grass jelly plant, and bring it home with me to the States. Until then, the canned version in my local Asian grocery store will do just fine.
