Milk Kefir Sourdough Starter

In my Universal Pancake Recipe, I mentioned that a little milk kefir mixed with flour makes a good, low-commitment sourdough starter. Today, I'm going to go into a little bit more detail about how that works, and how to make and maintain your starter.

Let's start with the basics: What is sourdough?

For the purposes of this blog, sourdough is any dough which uses a starter culture containing a diverse mixture of wild yeasts and bacteria. Store-bought yeasts consist of a near-monoculture of the yeast species Saccharomyces cerevisiae (the same species as the yeast used for brewing beer, but a different strain). A sourdough starter contains both Saccharomyces cerevisiae and lactobacillus bacteria (the same stuff that makes lacto-fermented pickles and turns milk into yogurt). Unless you are growing your culture in a tightly controlled laboratory environment, it will also become home to lots of other types of wild yeast and bacteria, creating its own little ecosystem.

Weekend update, 1-4 March (Storm Emma!)

Well, we survived the "Beast from the East" and my first-ever snow day more or less without incident. On the first day of the storm, I arranged to work from home, but by around 9:30 the university decided to close up shop, so I got an unexpected 4-day weekend!

As someone who grew up in Los Angeles, I still get a little giddy whenever it snows even a little bit, and we had much more than a little snow this weekend. The cold weather didn't stick around in South Wales nearly as long as it did in other parts of the country, but my area did get just under two feet of snow over the course of two days, accompanied by 45mph winds. In spite of the giddiness, I confess I did worry a bit about our garden as the snow drifts rose over the tops of our raised beds and completely buried a large portion of our herb garden. I was very glad that that we'd finished the raised beds and put new cloche hoops and fleece over them.

By Sunday morning, the snow was beginning to thaw and I peeked outside to inspect the damage to our herbs, which weathered the storm without protection. Much to my amazement, the only casualties appeared to be a recently-transplanted garlic mustard and a couple of broad beans whose cover blew off during the worst part of the storm. Plants are amazing.
