In a pot, add Water (800 milliliter), Granulated Sugar (145 gram), Agar-Agar Powder (1 tablespoon), and Pandan Leaves (2) together. Stir mixture until boiling at medium heat. Turn off heat and stir for 1 minute, discard pandan leaves.
Pour one portion of the agar agar liquid (about 350ml) to another small bowl, add 2 drops of Rose Pink Food Coloring (to taste) into it and stir well. Add Milk (50 milliliter) to the remaining plain agar agar liquid, stir well.
Pour 100 milliliter of the liquid into the heart shape pan. Place pan in the freezer for about 1-2 minutes for the liquid to set. Take out the pan, use a small sharp knife and roughly scratch lines on the set jelly.
Then pour 100 milliliters of the rose pink liquid on top and place the pan back to the freezer for another 1-2 minutes. Repeat the same steps, white and rose pink liquid alternating until all liquid is used up.
Lastly, chill the agar agar jelly in the fridge for at least 2 hours. Remove jelly on to a serving plate and top with fresh fruits.
