I seem to have a fair amount of "discarded" starter in my fridge - Yes, I know you are suppose to throw it out, but I can't bring myself to do that and each time I refresh my starter, I toss the surplus into a container in my fridge. I add some flour and water into the mix when I remember and it stays fresh and sweet.
So, pancakes for breakfast using my recipe. They are just so nice - light and fluffy and the bicarbonate of soda counteracts the sour in the starter. Basically, you take about a cup of starter (no need to refresh), add an egg, some oil and powdered milk, a little sugar, salt and bicarb and there you have it. Mix it up and make your pancakes. How easy is that!
Now I need to work out what to do with the other litre of left over starter.
