To ensure a smooth, lump-free consistency, cook the flavored agar-agar mixture for each layer independently.
To avoid mixing, allow each layer to cool for three to five minutes while still being warm enough to stick.
To preserve distinct lines, let each layer set halfway before pouring the next.
To prevent upsetting the prior layer, pour slowly over the back of a spoon.
For a firm, lovely finish, chill for at least two hours once everything is put together.
