Every so often I get this urge to make or try to make sourdough...... and every time I fail....

I have obtained all linds of starters, and many very kind souls have sent me some of theirs to get started.

 But always the same, after about 3 days it stinks like strong paint. so I dump it.

 I have tried different flours, different water, still the same, now what can I do...

Many many years ago I  did manage some how to get a decent loaf, how I don't know. but it was a long long time ago.....Any ideas...... qahtan
