I did some agar agar for a bbq gathering tonight and took some step-by-step pictures of how it was done for reference for those who are interested.
First cook the coconut layer of the agar agar following the recipe that I have shared before. Pour it into a washed and shake dry mould. Leave it in the fridge to harden. Then use a cutter to cut out the pattern.
Use a skewer or cake tester to remove the cut outs and leave it aside. Leave the tray in the fridge while you cook the coloured layer.
Pour the cooked coloured layer over the prepared tray. Leave it to cool down and leave it fridge to harden. Cut out into individual square to show the cut out flower in each square.
I cooked another batch of coloured agar agar to be used with the cut-out flowers. I used individual tart moulds for them.
This is how it look like after unmoulding.
