Thankyou Paul, that's very interesting, a solution to the jelly problem. I'd like to try that. I haven't had any jelly since I started hanging wild garlic in the windows, but I'm sure they'll outwit me in the end. Maybe I'll try making some purpose-built jelly. I treated some high-FFA oil with slaked lime, as instructed. I'll let it settle for a bit then see what I can do with it. Thanks much. Regards Keith ------------------------ Yahoo!
