1. Boil azuki beans in water until tender - will take about 45 min. to an hour.
2. Prepare coconut agar-agar & mango agar-agar at close intervals:
3. Simmer ingredients for coconut agar-agar in a pot for about 5 min.
4. Simmer ingredients for mango agar-agar in a separate pot for about 5 min.
5. Spoon in boiled azuki beans into mould. Pour prepared coconut agar-agar into mould and let it set briefly in the fridge - don't let it set all the way (maybe about 3/4 of the way through). Now pour the hot mango agar-agar over this first layer - this ensures that the mango agar-agar layer gels onto the coconut agar-agar and doesn't fall apart when cooled completely.
6. Let the whole thing set for about two hours before unmoulding.
