I have my first ever sourdough starter going and am on day 6, it is going very nicely, The temperature where i live is warming up now as we are going into the Australian summer. anyway back to the starter, there are many lovely bubble throughout and it is very froffy, once I feed it, it at least doubles in size if not more, then by the next morning it goes back down (I feed it around 11 am) I assume it is normal for it to go back down. The smell is lovely and sour with a tinge of fruityness. When is it best to use the starte, when it comes up? As I understand it before using it you refresh the starter anyway, wait some hours and then use it and keep the left over in the fridge until you are ready to bake again. do I have that right? thanks to anyone out there you can give this novice a bit of advice.
