Brilio.net – Black grass jelly is a mainstay ingredient for various fresh drink creations, from mixed ice, milk ice, to coconut ice. Unlike jelly from seaweed, black grass jelly comes from the Platostoma palustre plant. Its cool taste in the throat makes it a favorite when the weather is hot or when it’s time to break the fast.

However, the main problem with grass jelly is its short shelf life. If stored incorrectly, grass jelly quickly becomes slimy, smells and tastes sour. Fortunately, a netizen named Endah, through her YouTube channel, shared an effective method for keeping grass jelly quality for up to 30 days.

Steps for storing grass jelly so that it lasts 1 month

The following are the steps you need to take after buying black grass jelly from the market:

1. Cleaning and Cutting

Wash the black grass jelly thoroughly with running water to remove any dirt stuck to it. Once clean, cut the grass jelly into cubes according to your taste so you can use it later when making drinks.

2. Short Boiling Process

Boil water until it boils, then add the grass jelly pieces. According to Endah, the key is not to take too long.

“We just boil it until it boils once, don’t forget to stir it so the water doesn’t overflow,” the message was quoted as saying BrilioFood from YouTube Dapur Endah Reni, Monday (23/2/2026).

3. Rinse with clean water

After the water boils once, immediately drain the grass jelly. Prepare a container filled with clean, cold/room temperature water to rinse it. This process is important to remove remaining mucus and stop the ripening process so that the texture of the grass jelly is not destroyed.

4. Storage in an airtight container

Drain the grass jelly again until it is completely coarse, then put it in a jar with a tight-fitting lid. With this method, Endah guarantees, “This is the result, grass jelly that is coarse, chewy and has no smell.”

5. Store in the refrigerator

Place the jar containing grass jelly on the refrigerator shelf (chiller), not in the freezer. Grass jelly is ready to be used at any time for the family takjil menu.

FAQ Saving Grass Grass

1. Why does grass jelly have to be boiled before storing?

Boiling functions to kill bacteria and microbes that cause grass jelly to go stale quickly and have a sour smell. This is a simple sterilization process so that the grass jelly lasts longer.

2. Is it OK to store black grass jelly in the freezer?

Highly not recommended. The freezer temperature will damage the structure of the grass jelly cells, making them soft, watery, and lose their elasticity when thawed.

3. Should grass jelly be soaked in water in a jar when stored in the refrigerator?

It is best to store it drained (without soaking water) in an airtight container if it has gone through the boiling and rinsing process. This keeps the texture firm and doesn’t get soft quickly.

4. How long does grass jelly last if not boiled?

Without the boiling process, grass jelly usually only lasts 2-3 days in the refrigerator before it starts to become slimy and smell strong.

5. What are the signs that black grass jelly is no longer suitable for consumption?

If the surface of the grass jelly feels very slippery/thickly slimy, emits a sharp sour aroma, and the texture crumbles when touched, it should be thrown away immediately because it is stale.
