I started this about 5 years ago and it has been dried for about a year as I didn't have enough time to take care of it and bake with it.
I'm now trying to rehydrate this starter – it is 50% bread flour/ 50% water.
After 4 days of feeding it once a day it was starting to smell nice but I forgot to feed it yesterday and now it's got a yellowish layer on the top and doesn't smell that good.
Should I discard all the yellow, feed it and go on or do I need to toss it and start again with the last of the dried up starter.
