Hi! I'm new to the world of Sourdough and I bought a starter from a local Craigs List ad. I am a little unsure of what I should be doing and was hoping I could get some help here! The starter has been refrigerated for a week and is due to be fed today. Do I let the starter warm up before feeding? About how long will it take to warm up if so, would leaving it on the counter over night before feeding be ok? Also I have about a cup of starter, how much flour and water should I use to feed when I do feed, and does the flour have to be sifted? Sorry for all the questions, if someone can give me some advice or point me to some good instructions I would appreciate it! TIA!
