(Experiment 25) Sourdough starter

Sourdough starter

So my kids keep bugging me about this: WE WANT BREAD!

I can make the classic white stuff… it’s okay, but definitely not WOW. So for a few years, I’ve been putting off giving sourdough a spin… well, no more. The following is my interpretation of Joshua Weissman’s sourdough recipe, along with my notes.

There are multiple recipes available online, such as this one, made with all-purpose flour only.

Update: I had to transfer my starter to a normal rectangular glass container, and it’s definitely not ideal. Got myself a deal on a Weck jar set on Amazon, and what a difference it makes — much easier to mix.

(Experiment 25) Sourdough starter

Ingredients

  • Rye flour
  • Unbleached flour all-purpose
  • 850 ML container glass and tall are preferred with a loose-fitting lid
  • Water

Instructions

    I recommend to use source water instead of tap because it contain chlore and can destroy the good bacteria and alter taste.

Day 1

  • Weight your jar and write it down somewhere or better yet put a sticker on the jar with the weight on it. This will make each day maintenance easier
  • 100 gr rye flour
  • 150 gr lukewarm water ( ~85degree F)
  • Stir until no flour clumps , cover with a loose-fitting lid

Day 2

  • 24 hours later
  • Take you jar and weight it. For instance if jar weight 500gr, it should now be 700+ as we added flour and water in the jar.
  • Remove some of the mixture until you only have 70gr of the starter in the jar . Again as we weighted our jar, we know it should weight 500gr ( jar weight) + starter 70gr = 570gr total
  • You can discard all the extra starter we wont need it
  • Add to the jar :
  • 50gr rye flour
  • 50gr all purpose flour
  • 115 lukewarm water
  • Stir
  • Put loose cover

Day 3

  • 24 hours later
  • Repeat day 2
  • PS: Day 3 & 4 I didn’t see much activity , no need to panic keep the routine. In my case Day 5 it started to rise and fall again .

Day 4

  • 24 hours later
  • Same as day 2 but reduce water to 100ML instead of 115ML

Day 5

  • Repeat day 4

Day6

  • 24 hours later
  • Same process but with the following amount
  • 50gr starter
  • 50gr rye flour
  • 50gr all-purpose flour
  • 100g water lukewarm

Day 7

  • On the final day, again the same process but reduce starter
  • 25g mature starter
  • 50g stoneground rye flour
  • 50g unbleached all-purpose flour
  • 100g room temperature water
  • Note that you need to repeat day 7 every ~24 hours. If you forget it 1-2 days, you should be able to bring it back to life by feeding it again ( day 7)

In the fridge

  • If you don’t plan to bake a lot with it, you can put it in the fridge and feed it every 7 days, you can stretch it for 14 days if you want but you will need to do a few discard prior usage .
  • Feed it as usual and let it sit 1-2 hours at room temperature then place it in the fridge. After 7 days ( or less), let it come to room temperature and feed it using the same pattern as “day 7”. Let it sit at room temperature for 1-2 hours and then you can put it back in the fridge
  • If you plan on using the starter to make bread, it is preferable to take it out of the fridge 1-2 days in advance to get it activated again by doing a daily discard.
