I have a small bit of starter from someone I met recently.
The instructions that came with it don't make much sense to me and I have no way to contact.
Can anyone decipher?
100%, 1/2 WW, 1/2 white x.022=weight
70% water
10% sourdough
12 hrs.
total weight 180 IE: .400/180=.022
Take total weight of starter you want IE: .4g divide by total of percentages IE: 180.
Then multiply by each percentage for weight.
I'm assuming this formula is for feeding? Let's go through it line-by-line.
100% 1/2 WW, 1/2 white x.022=weight
This is where you start. For example: 200g whole wheat + 200g white, total of 400g, representing 100% of flour weight.
70% water
This means you incorporate 70% of your flour weight in water into your starter. For example, 400g * .70 = 280g water
10% sourdough
This means you incorporate 10% of your flour weight of leftover starter during your feedings. For example, 400g * .10 = 40g starter. The rest of the starter you need to discard.
12 hrs.
Not sure...this may mean to let rise for 12 hours before using...or it could mean you need to feed your starter every 12 hours.
Does this help at all?
ah yes, that does. So I guess what she gave me is the 10% and I'll have to build from there?
yes sounds like it. good luck!
