You can use whatever fruits you want, just make sure you cut them into smaller chunks. Cut the mango and grapes into small chunks. Remove the leaves from strawberry and halve the strawberries and then thinly slice them
Combine coconut milk, sugar, coconut sugar, salt, agar agar powder.
Bring it to a gentle simmer. Remember that this is coconut milk and you DO NOT want to boil the coconut milk over high heat as it will “break” and separate. Just let it simmers over medium-low heat and keep stirring until you don’t see any more agar agar powder, about 2-3 minutes.
Gently pour it over to the large mould and pop any bubbles with a toothpick. Let it set at room temperature until it is firm enough to hold the arrange cut fruits and next layer of agar agar. See notes about letting it set in the refrigerator
Arrange cut fruits:
Once the first layer is set at room temperature, arrange the cut fruits on top of it and put it back into the fridge
While waiting for first layer to set, combine water, sugar, and agar agar powder
Bring it to a boil and stir at the same time until no agar agar powder is visible anymore, about 2-3 minutes
Very gently, pour this on top of the fruit to minimize air bubbles as much as possible. Use a toothpick to pop any large bubbles you see. This layer takes a bit longer to set as it is thicker. It may take a bit longer to set at room temperature
While waiting for second layer to set, combine coconut milk, sugar, coconut sugar, salt, agar agar powder. Pretty much the same with the first layer again. Bring to a gentle simmer and stir at the same time until agar agar powder is no longer visible. Pour this on top of the second layer and let it set slightly at room temperature and then transfer to a fridge to chill for at least another 1-2 hours before unmoulding and cutting the cake
Unmoulding and cutting:
Use a sharp thin knife to gently run through the edge to loosen. Place a plate on top of the mould and flip it over. Cut into the desired size
If you want to let the agar agar layer set in the refrigerator to save some time, make sure you don't let it set in there until it is solid cold. When that happens, the next layer that you pour on top of it will not stick and each layer will not adhere to each other well when you cut the cake later. Just make sure you let it sets until it's firm enough to hold the next layer but not too cold and too solid.
If you use agar agar flakes or agar agar strands: use 2 Tbsp agar agar flakes (8 gr) or 24 agar agar strands (8 gr). If you use agar agar flakes:Dissolves it in the liquid (not hot liquid) you are going to cook and then put on the stove and bring to a boil until it dissolves completely. If you use agar agar strands:1. Cut into 1-inch pieces or shorter so you can measure with measuring cup2. Soak them for 15-20 minutes3. Put in a liquid you plan to use and bring to a boil and boil until the agar agar dissolves completely
