Jello

Hello,

I am teaching a class in Malaysia and do not know if I can get Jello. Will agar agar work? It is their version of jello, yet denser. Just thought I would ask, before I try it out myself. :)

Thanks.

Agar agar versus Jell-O

Submitted by iwaldron on Tue, 08/02/2011 - 8:20am.

I don't know the answer to your question, but I believe that as long as agar agar contains protein, sugar and water, the results should be the same.  Please let us know what you find out.
