Kilner Sourdough Starter Set, Glass, 350 milliliters - £7.95 @ Amazon

I saw those in Dunelm store for 2 quid a week ago. You can basically use mayo jar for this purpose.

I make a lot of sourdough and use these. Everyone saying you don't need this is of course correct, but, these do a good job and this a good price. The jars have straight sides to the top which is easier to work with than say a reused mayo jar that usually curls at the top, and the lid makes it easy to leave it slightly open to allow gas to escape. The scraper is decent. The measuring cup lid I don't use, I always weigh the water and flour. Elastic bands are handy but you'll soon be good at judging it by eye or using the measures on the jar. Only issue is it's a little smaller than I'd like. I make up about 220g of starter, use about 190g leaving 30g for the starter but that does make two large 900g loaves. If your starter is particularly active it might overflow a little at that level (but that's not a big deal). I tend to cycle the jars - starter lives in fridge until I need it, make up new batch in second jar and clean the original.

I buy my sour dough from Marks and Spencers for £33 a loaf.

Any big jar will do

Does anyone use a bread maker to bake their sourdough? If so, how?
