120-Year-Old Sourdough Starter

Rising fame: experts herald Canadian woman's 120-year-old sourdough starter

Every Saturday night for the last sixty years, Ione Christensen has followed the same routine to prepare waffles for breakfast the following morning: she measures out two cups of flour and two cups of warm water, then she reaches into her fridge to bring out her sourdough starter.

“It’s a family pet, if you will,” she said from her home in Canada’s Yukon territory.

Like any pet, the starter needs to be constantly fed – in this case, with flour and water.
