At a glance
Building a sourdough starter is easier than most people think – you're just mixing rye flour and water, then feeding it daily for a few days while it ferments on your counter. The hands-on work is minimal (just stirring and adding ingredients each day), and by day three or four, you'll have an active starter that's ready to make some seriously delicious bread.

Mix and cover with cling film
Stir thoroughly so there are no lumps left in the mixture. Cover the bowl (or a large jar, depending on what you're fermenting your starter in) with cling film. I just left the bowl sitting out on the counter at normal room temperature.

Day two: feed it
The starter is hungry, so it needs feeding. Stir in more water and flour, mixing thoroughly – watch out for lumps! Leave it to develop for another day and enjoy watching it grow nicely.

Day three: feed it again
If you like, you can taste how the starter is coming along. It should taste pleasantly, mildly tangy. I had pretty much ideal conditions, so my starter was already usable on day three – I didn't need to wait until day four.
