So very true!@chickmom3941 try not to overthink the Sourdough Starter. It is pretty easy. Considering it traveled across this great country in a covered wagon, you got it handled. Mine just came out of the fridge after 2 months of neglect - no feeding, stirring or anything. Added flour and water and it is right as rain. It made muffins just fine.
If it has been in the fridge for a long time, I will toss half of it and add half a cup of flour. Several hours later or over night, I will add more flour and a bit less than the half cup of water. It always comes back!
Only toss if it turns pink. Pink is bad for sourdough....good for raspberry buttercream frosting though!
