Bring apple juice, apple, raisins and agar to a boil. Simmer for 10 minutes.
Pour into individual bowls and let cool. The agar will gel as it cools.
In a separate pot, bring water to a boil and add the cashews. Cook for 10 minutes until they are soft.
Strain cashews and put in a blender with a little of the cooking water.
Add rice syrup and blend into a creamy paste.
Add cream to the top of the apple kanten and garnish with some black sesame or roasted cashews.
Notes
Agar agar is the Malaysian word for jelly and is a natural and vegetarian substitute for gelatine (Kanten is the Japanese word for it). Wikihow has more details if you are curious.
It's generally easier to find agar powder than raw agar (which looks like a a long stringy white seaweed). If you get the seaweed form you need to use a lot more of it, in this recipe use about a cup (a decent hand sized chunk of strips).
Brown rice syrup can be hard to find, honey makes a good (though less Macrobiotic) substitute.
