Hi there, greetings from The Netherlands, neighborhood of Gouda and Leiden. I'm using PVA coating a lot for my pressed cheeses, just like all the artisan and "factory" Gouda's are treated here. Why would you try to make the coating yourself? Don't you have suppliers for it in SA? Here it is fairly cheap (about 9 euro's per kilo and cheaper in bigger quantities) so for me it would hardly be worthwhile to make it myself, providing that I knew how....
