Secret to Making Crispy, Delicious, and Absolutely Non-Weeping Agar Jelly (Rau Câu) with Hoang Yen Hai Phong Powder
Do you love the refreshing taste of agar jelly (rau câu) but often find that your jelly turns soft, mushy, and weeps water when left out? Worry no more! With a precise secret recipe and high-quality ingredient – Hoang Yen Hai Phong Flexible & Crispy Agar Powder – you can easily make perfect batches of jelly: wonderfully crispy and chewy, completely transparent, and guaranteed not to weep, maintaining its freshness for a long time.

Why Does Your Agar Jelly Weep Water?
The phenomenon of agar jelly weeping (syneresis or water separation) typically occurs when water components separate from the gelling structure. The main reasons include:
-
Incorrect Water/Powder Ratio: Too much water compared to the amount of agar powder.
-
Using the Wrong Type of Powder: Using agar powder with low binding strength or one that contains too much Carrageenan (a substance that can easily cause water separation).
-
Improper Storage: The jelly is chilled too quickly or subjected to sudden temperature changes.
Using Hoang Yen Hai Phong Agar Powder is the first and most crucial step to thoroughly solve this problem, thanks to its special formula that enhances binding and results in a crispy-chewy texture.
Detailed Guide to Making Crispy, Delicious, and Non-Weeping Agar Jelly
Here is the standard recipe, guaranteeing 100% success when using Hoang Yen Hai Phong Agar Powder.
1. Essential Ingredient Preparation
| Ingredient | Standard Quantity (For Coconut/Coffee Jelly) | Notes |
| Hoang Yen Flexible & Crispy Agar Powder | 1 pack (25g) | Ensure you use the flexible & crispy type from Hoang Yen for the best chewy texture. |
| Granulated Sugar | 250 - 300g (adjust to taste) | Sugar helps enhance the binding; do not reduce the amount too drastically. |
| Filtered Water | 1 - 1.2 Liters | This is the "golden ratio" to prevent weeping! (Equivalent to 1000 - 1200ml) |
| Flavoring | Coconut cream, coffee, pandan extract... | Optional, for color and flavor. |
2. Precise Cooking Technique (The Anti-Weeping Secret)
Step 1: Dry Mixing (Preventing Lumps)
-
Thoroughly mix the Hoang Yen Agar Powder with all the measured granulated sugar in a dry bowl.
-
Note: Do not soak this agar powder directly in water before cooking, as it easily causes clumping. Mixing it with sugar helps the powder dissolve evenly when added to the boiling water.
Step 2: Cooking and Dissolving the Powder
-
Boil the prepared filtered water (1 - 1.2 Liters).
-
When the water is gently simmering, turn the heat to the lowest setting (or temporarily turn it off).
-
Gradually sprinkle the mixed sugar and agar powder into the pot, while stirring quickly and continuously in one direction only.
-
The Secret: Stir gently for about 3-5 minutes until the powder is completely dissolved. Then, turn the heat back to low and simmer for another 1 minute. The purpose is to fully cook the powder, resulting in a firm and crispy structure.
Step 3: Skimming Foam and Separating Colors (Maintaining Clarity)
-
Skim off all the foam on the surface to ensure the jelly is transparent and beautiful.
-
Divide the cooked jelly mixture into equal parts for coloring/flavoring (e.g., one part for coconut cream, one part for coffee).
-
Important: When adding coconut cream or milk, ensure they are pre-warmed before adding to the agar to avoid a sudden temperature drop, which can cause separation.
Step 4: Pouring and Chilling (Ensuring Crispness)
-
Pour the colored jelly into the mold, ensuring the next layer is poured when the previous layer is set but not completely hardened (it should not stick to your finger when touched).
-
Let it cool completely at room temperature (about 1-2 hours).
-
Absolute Anti-Weeping: Only place the jelly in the refrigerator's chill compartment after it has completely cooled down. The chilling process should be slow and continuous. Do not put it in the freezer or subject it to sudden temperature changes.
Tips for Storing Agar Jelly Without Weeping
-
Stable Temperature: Store the jelly in an airtight container in the refrigerator's chill compartment (ideal temperature is $2^\circ\text{C} – 8^\circ\text{C}$).
-
Avoid Air Exposure: Cover or wrap with plastic wrap after cutting the pieces to prevent the surface from drying out and weeping water.
-
Optimal Time: Homemade agar jelly should be consumed within 3-4 days to ensure the best freshness and crispy-chewy texture.
With Hoang Yen Hai Phong Flexible & Crispy Agar Powder and this standard recipe, you will confidently create batches of agar jelly that are not only delicious but also maintain a perfect structure.
