High quality of agar agar powder

I recently found a recipe for making your own vegan cheese using Agar Agar that I wanted to try.Has anyone else here used Agar Agar and  if so, what did you think?I've never used Agar Agar, but are you saying that your nutritional yeast cost 7-10 bucks for that small amount?!  I can get a pound for $5 in the bulk aisle of Whole Foods...are you sure you were looking at the right stuff?I found it. take a peak and let me know what you think Dani. Sounds yummy but man that stuff is really expensive.  Amazon sells the agar agar too.
Go to your local natural foods market. They usually have agar agar in the bulk supplies. Your natural foods store should also have a supply of gelatin-free candies such as lollipops and gummy bears.
Then add in the rest of water, screwpine to boil for 10 mins, to bring out the screwpine's fragrance.Off the heat, remove the screwpine so that agar agar will not be wasted as it will stick to the screwpine. Stir in the washed agar agar as food additives strands and coloring OR lychee/longan juice.The strands need to be dissolved and the mixture look syrupy and have a slight gel consistency.
Another option is to use a big wet mould or cake tin and then cut them up into shapes/wedges etc. For this, do not add extra water, as you will need firmer agar agar to cut into pcs, otherwise the agar agar will break easily.I purchased some agar agar to try. I'd like to know if after I disolve it in water can I add flavored oil to it and still expect it to jell ?
