After hearing someone from this site on the radio I got all keen and checked this site for recipes and such.
I got in and commenced my starter and left it to grow and fed it the second night.
However, then I got busy and forgot about it. I forgot it for about 1 1/2 - 2 1/2 days. When I remembered it was all bubbly (not quite ready bubble wise) but it was also quite smelly - probably a normal 'sour' smell if I remember from making the Amish friendship cakes (although the smell of that did turn me off the cake!).
Should I keep feeding it now or is there the possibility that it could have gone off?
