sourdough starter from nourishing traditions

[babywearer_anon]

I made the starter and then the sourdough bread from the Nourishing Traditions cookbook.

It turned out pretty well for a first run. its pretty heavy and dense, but i like it that way!

What do you do with the leftover starter after you bake your bread?

I put it in the fridge. But I'm wondering how long it will keep in there?

I only want to bake bread every 2 weeks or so.

After a couple of weeks, can I take it out and build it up again on the counter?

How long before the starter is recharged enough to bake with?

Also wondering what else people have made with the starter. The recipe i have makes a huge amount.

I did find a recipe for sourdough english muffins which sounds kind of good.

One final question - (sorry so many!) what kind of flour works best for bread?  I used whole spelt as the recipe calls for. But my friend uses sifted/unbleached 'white' spelt and she says that works well.

Thanks!!
