All About Sourdough
A Living Tradition In The Kitchen
Sourdough is one of the oldest and most time-honoured ways of baking bread. Long before commercial yeast existed, bakers relied on naturally fermented mixtures of flour and water to leaven their loaves. Evidence of sourdough bread dates back to around 3700 BCE, with archaeological finds of ancient loaves discovered in Switzerland and connections to Egyptian baking practices using clay pots more than 4,500 years ago.
These early bakers unknowingly harnessed the power of wild yeast and lactic acid bacteria that live naturally in our environment. When flour and water are mixed and left to ferment, they create a symbiotic culture known as a sourdough starter, or “mother dough.” For thousands of years, this living culture was the primary method for raising bread, until Louis Pasteur’s work with yeast isolation in the 1850s led to the commercial yeasts we commonly use today.
When people speak of having a “100-year-old starter,” it doesn’t always mean the exact same mixture has remained untouched for a century. Starters are continually refreshed with new flour and water, allowing them to evolve with their environment over time. While the original microbes may change, the practice itself connects directly back to those ancient baking traditions; a beautiful blend of history and living culture.
Creating and Maintaining a Starter at Home
Making a sourdough starter at home is wonderfully simple, though it does require a little patience. Flour and water are mixed together and then fed regularly, allowing natural fermentation to develop. Over time, the mixture becomes bubbly, fragrant, and alive; ready to help your dough rise and develop that signature sourdough flavour.
Of course, another lovely option is to find someone who already has a starter they are willing to share. Passing along a portion of starter from one baker to another feels a bit like sharing a piece of kitchen heritage.
In my own kitchen, I keep a small amount of starter tucked away in the fridge. When the mood strikes to bake some sourdough goodies, I simply take it out and give it a few good feedings until it becomes lively and active again. This keeps maintenance simple and manageable while still allowing me to enjoy sourdough whenever inspiration hits.
Maintaining a Starter Without Excess Discard
I try to maintain my starter carefully so there is very little waste. By keeping a smaller quantity and feeding only what I need, I can minimize or even eliminate discard most of the time. Because of this, when a recipe specifically calls for sourdough discard, I actually have to plan ahead and create some; rather than having jars of it sitting in the fridge.
So, what exactly is sourdough discard? It is simply the portion of starter that is removed before feeding to keep the culture balanced and healthy. While some bakers collect and store their discard for recipes like pancakes, crackers, or muffins, others (like myself) prefer to keep things simple and only create discard when needed.
My Sourdough Journey
My mother dabbled with sourdough starters a little when I was growing up, but it wasn’t something we used regularly. Early in my marriage, I kept a starter for about a year, though I didn’t fully take the time to learn all the ins and outs of working with it. Like many others, my interest in sourdough grew during the pandemic when home baking became both comforting and practical.
I’ve now had a starter for a few years, baking different sourdough recipes here and there. My children enjoy some sourdough treats, though not all; they aren’t always fond of the stronger tangy flavour coming through in every recipe. Because of that, I often set aside promising recipes and, when time allows, try several at once to see which ones become family favourites.
It’s a gentle process of experimenting, tasting, and discovering what works best for our home and our preferences.
Sharing the Journey
Sourdough baking is as much about the process as it is about the final loaf. It invites you to slow down, observe, and nurture something living right on your kitchen counter. Each batch is a little different, shaped by the seasons, the flour you use, and even the air in your home.
Here, I’ll be sharing photos and recipes of the sourdough creations that have turned out especially well and earned a place at our family table. Some may be perfectly tangy, others mild and soft, but all of them are made with care and curiosity.
Sourdough is not just bread, it’s a tradition, a science, and a cozy rhythm in the kitchen that connects the past with the present, one loaf at a time.
