I don’t know how familiar you are with Sourdough Bread. It’s been around for a very long time. Although it can be made from a starter culture from someone else, it can also be made from scratch. It’s made with flour and water and is fed more flour and water each day. I’ve never made Sourdough Bread from a culture or from scratch.
After studying how to make it in an article by Emma Christensen, I am inclined to give it a try. You’ll find all you need to know by searching the internet for Emma Christensen, How to Make Sourdough Bread.
All it takes is flour, water, and time. Soon you’ll be able to share a culture and some tips with a friend and let them learn the joy of making Sourdough Bread.
