There are some old threads here asking what to do with discarded starter; rather than revive them, I just thought I'd say that I tried out King Arthur Flour's Sourdough Crumpets recipe and it is love!
They're quick to make and the recipe uses a full cup of discard--and, maybe more importantly, it doesn't need any added flour (my search for bread flour today came up empty; I'm not out, but I'll have to husband it).
So far I've made crackers, pretzels, and these with the discard, and this is my favorite recipe--not only are they good, but I can make a batch in about 10 minutes total.
Great idea! Thanks for the reminder...
