My gran used to make these all the time when I was young, and I'd forgotten all about them. She died nearly five years ago, and I was given a Herman starter thing the other day by my best mate and I really want to make it work. I have two questions though - first of all, do you have to do it over 10 days (as am going away in 5!) and secondly, if the starter has eggs and milk in it, does it not go funky if you leave it lying around for 9 days?
Anyone know what am on about?
