Hi there

Probably a dumb question, but I've spent ages googling and reading
this group and can't find an answer anywhere.

I'm trying to grow a starter using the following method -
1. Start with 50g flour and 50g water
2. After 24 hours add another 50g each of flour and water
3. After 24 hours throw half away and add another 50g each of flour
and water
4. Repeat 3 until the starter is ready

I'm growing it in a cylindrical glass measuring jug. After 3-4 days I
have a layer of pale brown liquid which has formed in the middle of
the starter. There is evidence that it's bubbled up and it otherwise
appears healthy (no pinkish liquids, no mould) but I'm worried about
the liquid forming in the middle. Is this a problem? Is it because
I'm not feeding it often enough?

Thanks

Simon
