No-knead bread from frozen sourdough starter

A while back a kind friend gave me some sourdough starter, along with two lots of instructions to make no-knead bread with it.  I love sourdough, plus it's good for me as it's low GI, so no-knead sourdough sounded like a winner!

Unfortunately, the instructions involved making bread frequently in order to keep the starter alive.  I don't eat much bread, so that wasn't going to work for me.  I was sure that the culture would survive freezing, but I couldn't find any information on how to go about freezing and reviving it.

After some experimentation, I seem to have come up with a method that works reliably:

• Freeze your sourdough starter in 1/4 cup lots (I put 4 or 5 'blobs' of it on a silicone tray in the freezer, spaced well apart as my starter is quite runny).  When they're frozen, store in a ziplock bag in the freezer.  I don't know how long they keep like this, but definitely at least 6 months.
• A few days before you want to bake your bread, take one portion of starter out of the freezer and put in a bowl.  Mix together 1/2 cup flour and 1/2 cup water and spread over the starter.  Put it in a warm place (I use the hot water cupboard when the weather's cold) and cover loosely with a cloth.  Don't cover it with a plate - the starter needs to 'breathe'.
• When the starter has thawed, stir it all together.  Check from time to time.  When it's risen and covered in bubbles (which will probably take 1-3 days) it's ready to either use or, if you need a large amount of starter, feed again.  Further feedings should be at approximately 12-24 hour intervals.*

NB If it separates into whitish sludge with yellow/green/brown/grey liquid on top don't worry - that's alcohol separating out.  Stir it back in and feed it/use it when that happens.  The only time to discard it is when you see hairy mold on top (in which case just remove those portions, don't throw the whole thing out) or when the liquid on top smells foul - not just of acid and alcohol (in which case throw it all out).

*  To feed, stir it (so you can see how much you have); add about twice this volume of flour and about this volume of water (i.e. equal parts by weight); stir to mix; then leave it.  It should produce enough gas to double in volume by its next feeding, so your container should be big enough to cope with this.
 
The bread recipe I use is as follows:

Ingredients:
6 cups flour (1:1 wholemeal:white is nice)
1 T salt
3 T sugar
1/2 - 3/4 cup sourdough starter (revived from 1/4 cup frozen)
3 cups water

Method:

1. (at noon) In a large bowl combine flour, salt and sugar. Add starter then water and stir until blended; dough will be very soft and sticky. Cover bowl with paper towels**.  Let dough rest at least 12 hours, preferably about 18, at warm room temperature (e.g. in the hot water cupboard).
2. (9.15 am) Check the dough.  If it hasn't risen much (or at all) and is quite runny under a crust/skin, stir in extra flour till it's only sticky - this generally takes around 1 1/2 cups flour.
3.  Work the dough a little, folding it on itself till it doesn't get any smaller (should take less than a minute), then separate the dough into two balls. Generously coat a baking tray with flour, wheat bran or cornmeal; put each dough ball on the tray and dust the tops liberally with more flour, bran or cornmeal.  Cover loosely with paper towels** and let rise somewhere warm for at least 2 and preferably 5-6 hours.
4. (3 pm) At least 20 minutes before you bake the dough, heat oven to its hottest setting - around 250°C. Put two heavy oven-safe containers (cast iron, enamel, Pyrex, pottery or silicone; anywhere from 5-cup capacity up is fine) in oven as it heats, along with a shallow pan with a cup or so of water in it.
5. When dough is ready (3.30 pm), carefully remove pots from oven.  Drop the risen dough balls flour side down into the containers; it may look like a mess, but that is O.K.  Don't worry if they've barely risen at all - they should still rise during baking and be fine.  Shake pan once or twice if dough is unevenly distributed; it will straighten out as it bakes. Bake uncovered 30 minutes.  Turn onto a rack and leave to cool.

This bread freezes beautifully, so I usually slice it when it's cool, freeze those slices on a tray then reassemble them into a loaf.  That way I can just take out a few slices from time to time as I need them :-)

With thanks to http://www.sourdoughhome.com for helping me to understand sourdough better so that I could develop a reliable method for making my bread :-)

** In general I'm not much of a fan of paper towels, preferring washable reusable cloths instead.  However, after gumming up our washing machine with the tiny scraps of dough that had accumulated from many months of washing teatowels used this way, I came to realise that using compostable paper towels is much more sustainable than wrecking our washing machine!

BU Kofi

Martin and I are excited about a new project that the Baptist Union of churches in New Zealand is involved in.  In partnership with the Baptist Union of Papua New Guinea, they are starting up a fair trade coffee growing and processing business.  It will be established in the Baiyer Valley in the Highlands region of PNG and be called 'BU Kofi'.

You can read more about the project here*, but the things that appealed to us are:

1. the project has been initiated by people from Papua New Guinea (rather than foreigners);
2. they see this project as being important in peace-building in an area that has seen a lot of conflict in recent times;
3. their process has been guided by a World Bank report into the coffee industry in PNG, so they won't be making the same mistakes as have been made by others in the past (although of course they can make new mistakes and they still see this as a high risk endeavour).

The Baptist Union of PNG is asking the Baptist Union of New Zealand to help them financially in this endeavour.  As I've spoken about earlier, I've been really challenged in recent years by the story of the Good Samaritan in Luke 10.  In it, Jesus seems to be saying that we have a responsibility to help our neighbour, and defines our neighbour simply as anyone who asks for our help.  In the light of that, Martin and I decided to make a small contribution to help out our neighbours in PNG.  If you would like to do the same, click on this link and select 'PNG coffee project' in the 'campaign' field.  They need to raise $100,000 over three years, in addition to funds already promised by NZAID and the PNG government.

* there's more information in the links in the orange 'recent articles' section at the right-hand side of the page.  We also have a pdf about the project that contains some information that doesn't seem to be on the website.  If you'd like me to email you a copy just put a request in the comments or email us here.
