sourdough is a very cool thing. every time you use the sourdough you take some of the starter to use and reserve some to stay in the fridge and keep the original strain alive. the oldest known starter is in san francisco at boudin bakery claiming 153 years.
when i was at home in alaska this summer i had my parents give me some of their sourdough starter that they’ve had for over 30 years that was passed down by a woman whose family reportedly had had it for over 100 years.
here is the story of this sourdough as told by my mother (and edited a bit by me):
We got this sourdough in 1982 in Edna Bay. We got it from a couple whose names were Michael and Jan. They had lived on their steel sailboat and got the sourdough when they lived on their boat and anchored in Port Alexander, AK from an older lady who liked them and their kid, Morgan. They built a
round house with cement, firewood logs, and the ends of wine jugs for light (in addition to some windows) on the land they bought on the island.
Anyway, the sourdough from the old lady in Port Alexander was from her 100 year-old starter since she was the offspring of original fisher folk who settled there in the early years.
We kept it going for years, eventually increasing it from a pint to a quart as we had more kids. We used to take it with us if we left the house for long periods in the winter to keep it from freezing. I would wrap it in a clean diaper and then put it in a ziploc bag and in my pack when we traveled (no restrictions on liquids in carry-ons.) It has been to Connecticut, Utah, Seattle, and San Diego during those trips.
So since we’ve had it the sourdough moved from the float house to the house on land in Edna Bay, to Ketchikan and now to Portland.
so, while it’s a super cool story, age reportedly only adds stability to starters, not extra deliciousness. damn. but that means you don’t have to wait 100+ years to have a sourdough pancake. check out joy the baker’s five or so day tutorial here on how to start a sourdough starter (i’m setting you up with her starting page, you’ll have to navigate the progression) since i’m not about to forsake the ease i’ve had in being given this starter anytime soon.
