Hi, I have made my first starter using a method I found online. It took 11 days and passed the float test. It was going fantastic and I made my first loaf last week. I was very proud however after I put the starter in the fridge and took it out to bake another loaf I noticed black specks through it. Is this my starter ruined? Should I throw it away and start again? Or is this just bit that were in the organic wheat flour? The starter was stored in a mason jar, I put a clean piece of cotton over it with an elastic band so that it could breath. It is still in the fridge but instead of cotton I have used a piece of baking paper to cover it. I used Gilchesters organic, wholemeal wheat, stoneground flour. Basically just wondering if it is safe to cook with or if I should start again doh!
