Easy get a culture,get a container,i use those throw away containers from the chinese,make sure when you add the mix you leave enough room for culture to climb the sides,in a few days they will be all over the lid aswell,,, mix some porridge with milk microwave it for about 40seconds, stir it well, and make sure its not to thick and not to runny,mix in a sprinkling of yeast<cheap from tesco/asda etc, then leave it to cool down,when cool,sprinkle some over the top and add the culture.....leave in a cool dark place,i kept mine in kitchen cuboard,after a couple of days it will have multiplyed and all you need do is run your finger around the pot scraping away any that are crewling up the sides, dont add the porride to water....
