I made my own starter a couple weeks ago: flour and water, and left it on the top of the fridge. I have been feeding the starter each day for the past two weeks.

I have not discarded any. Now the more I am reading I see I should have discarded half of the starter before each feeding. (Still not clear if that is only the first week or always?)

For each feeding I used the same amount of flour and water like I did on the first day, regardless of the growing amount of soupy starter in my super large jar. It has smelled fine, I have even baked with it a few times.

Do I have to start over or can I use this?
