Scrapings Method

That moment you realise that you miscalculated the amount of starter you needed and you're left with almost nothing.. Don't worry, all is not lost! 

I left myself with about 8g of starter in the jar and I fed it 50g water and incorporated what was left and then added 50g flour mixed and then left. Later on that night (about 10hrs later) it had risen to over double (see second pic) and then the next morning it was nice and bubbly on the top (the third pic). You can build on a starter from the tiniest amount, but it just takes a bit of time.. It's actually a method some people use called the 'scrapings method' where you always calculate exactly what you need and use all of it and whatever is clinging to the sides of the jar is what you build on next time. It can save a lot of flour.. but I feel a little more comfortable keeping my usual 50g for next time!
