On each of the first five days, put equal amounts of flour and water into your container, mix, close and leave at room temperature (about 20°C/68°F) for 24 hours between each addition.
For the first few days, the mixture might seem lifeless and could smell vinegary or even a bit “off”. Don’t worry about this, as it should soon start bubbling and the smell will develop into something yeasty and maybe even floral.
Once your starter is bubbling up nicely, you can use some to bake a loaf of Real Bread. Typically, this might be anything from four to seven days after you started, but could take a little longer. If it’s not bubbling by day six, keep repeating the daily flour and water addition until it is. Don’t worry if you end up with a layer of brownish liquid. This is just gravity working its magic and is normal. Either stir it back into your starter or pour it off. If your starter hasn’t been used for a while, the second option is probably better as the liquid (sometimes known as “hooch”) will have started to become alcoholic, which can slow the starter down and may also lead to less desirable flavours in your bread.
