I have only had it weep when I bind alcohol or very acidic components. The basic rules I know are to add agar to your liquid before heating and allow to hydrate. Bring to a boil and simmer for 90 seconds. Sugar can interfere with it activating, so in high quantities, add the sugar after your mixture has come to a boil. Once your mixture is set you will have a brittle gel or you can blend it to get a fluid gel. It is thermo-reversible.
