Go to the supermarket and buy one of these, actually get two. They are a lettuce crisper and I find them perfect for starter doughs. Good to see more Aussies here
To fit in with the "crowd" I actually bought a dozen (Well, two dozen now, because I bought the wrong mouth the first time) quart wide-mouth Ball Mason jars. These are the bomb mate, I keep an empty to tare my scales, and a few spares to change over every now and then.
I liked them so much I put them in our store to sell
You can get a half box pretty competitive off eBay, about $5 a piece, or you can order direct with Ball Mason Australia.
My starter doing nicely. Made one batch of pizza, one batch of pancakes yesterday, and I have a batch of Naan proofing for a bake tonight. With the colder winters here, mine is taking around 4-6 hours to peak activity.
