nickheer, I found this substance at the grocery store marked “gelatine halal sheets (vegetarian)” with no other information. They are transparent yellow-tinted thin sheets that are hard to snap and shatter a little when you do. I’ve dissolved about 10–15 grams in about 200 grams of stock and they do seem to be thickening it a little when left to cool. Any idea what this could be other than the gelatine I suspect it is?
