BTW, I think there is someone with a very similar name already on this forum??
Welcome Vanessa. You are going to love your machine. Here is the link to Isi's rolls. Like Gert I often make this as a loaf too.This is the link to the No Fuss rolls.Looking at the member list the other 'Vanessas' haven't posted and have been members for some time.
I would contact the consultant and tell her what you would like to cook at your delivery demo. Custards, sorbets etc are dead easy and you would be better off making something a little more substantial if you are able. One of the first things people make is the vegetable stock concentrate so that you have it on hand immediately but once again, it is so simple you may wish to disregard this one too. I'd tell her you want to make a meal, bread/rolls or a cake/dessert - or all three if possible. Have a browse of the forum and pick out some recipes that you are able to request.
