Ingredients (Serves 6-8 slices)

Basic Ingredients

  • 1/ 1 cup (250g) red bean paste – Choose smooth or chunky.
  • 2/ 1 1/2 tsp agar-agar powder (or 4g agar sticks) – Gives the jelly its signature firmness.
  • 3/ 1 cup (240ml) water – Helps dissolve the agar properly.
  • 4/ 1/3 cup (70g) sugar – Adjust to your preferred sweetness level.

Optional Variations

  • 1/2 tsp green tea powder – For a different flavor.
  • Chopped chestnuts – A traditional addition for extra texture.
  • Sweet potato puree – For a naturally sweet and earthy twist.

Step-by-Step Instructions

1. Prepare the Agar Mixture

To begin with, dissolve the agar:

  • First, in a small saucepan, add 1 cup of water and agar-agar powder (or agar sticks).
  • Then, stir well and let it sit for 5-10 minutes. This helps soften the agar, ensuring it dissolves properly.

Next, heat the mixture:

  • After that, place the saucepan over medium heat, stirring continuously.
  • At this point, keep stirring for about 5 minutes until the agar completely dissolves.

Pro Tip: If you’re using agar sticks, strain out any undissolved bits before moving forward.


2. Add the Sweeteners

Once the agar mixture is ready, incorporate the sugar:

  • Now, add 1/3 cup of sugar to the saucepan.
  • Then, stir well for 2-3 minutes, making sure the sugar fully dissolves.

After that, mix in the red bean paste:

  • Gradually, add 1 cup of red bean paste while stirring.
  • As you continue stirring, keep the heat on low and let it cook for another 5 minutes to ensure a smooth consistency.

For Green Tea Flavor:

  • If making green tea-flavored jelly, first dissolve 1/2 tsp green tea powder in 1 tbsp warm water before adding it to the mixture.

3. Pour and Set the Jelly

Now that the mixture is ready, prepare the mold:

  • Before pouring, lightly grease a small rectangular mold (or line it with parchment paper) for easy removal.

Next, pour the mixture:

  • Carefully, pour the hot jelly mixture into the mold.
  • At this stage, use a spatula to smooth out the surface and remove any air bubbles.

In the meantime, let it cool:

  • At room temperature, allow the jelly to sit for 30 minutes before transferring it to the refrigerator.

Finally, refrigerate until firm:

  • Once cooled, chill in the fridge for 2-3 hours or until the jelly has fully set.

4. Slice and Serve

Once the jelly is firm, remove it from the mold:

  • Now, gently take it out of the mold.
  • Using a sharp knife, slice it into rectangular pieces.

To serve, enjoy it with hot tea for an authentic experience.
