With folks staying at home with more time to cook and experiment in the kitchen, many are turning to sourdough bread baking as their new hobby. I am thrilled about this, as I think sourdough bread is the most nutritious form of bread we have available and making things yourself is an important value to me. With this renewed interest in traditionally-leavened bread, however, comes the issue of what to do with the sourdough discard. If you have cared for a sourdough starter before, then you are likely familiar with the feeding process of your little sourdough pet: you discard half of the starter, then feed it equal parts flour and water. This can be done daily for regular bakers or, in my case, one to times per week for less frequent baking. For the rest of the time, the starter is stored in the refrigerator until I am ready to feed it and bake with it. The discarding prior to feeding is done to keep your starter at a reasonable size (if you never discarded and did not bake with large amounts of starter, it would just get bigger and bigger!) and to keep microbial balance in the starter as well. If you are going through the steps of discarding and feeding daily, then you are going to be finding yourself tossing out quite a bit of sourdough starter. Not only is this unnecessary, but is also incredibly wasteful, which nobody wants, especially right now.
My strategies to reduce this food waste and continue to use as much of what I can from all of my kitchen projects are these:
1) Keep the starter in the fridge for the majority of the time, as mentioned above. Unless you bake bread daily or every other day, you do not need to keep your starter at room temperature and feed it everyday. Refrigerating the starter between bread bakes helps reduce the waste of regular discarding and feeding, plus it helps save on flour costs and helps keep it alive for longer in case you forget to feed it or need to leave for a few days. To "wake up" the starter before baking with it, simply feed it a bit of flour and water until it becomes bubbly and active, then it is ready to be used as leavening.
2) Keep a smaller amount of starter on hand. You really only need a small amount of starter at any given time to keep in your "reserves," at least for most home bakers. I typically have 1/4 to 1/2 cup of happy, healthy starter at any given time. Then, I feed it equal parts flour and water a few hours before use and any discard created will only be a small amount.
3) Save your discard to give away to others to start their own sourdough bread baking. I love the tradition of passing on starters and SCOBYs from one person to another, carrying on the magic of fermentation and keeping folks connected through food, which is important for us humans! I always like to keep a bit of extra starter on hand, as I always have people asking me for some, and now is the perfect time to keep up this tradition.
4) Use that discard in a delicious recipe! This is the most important strategy, I believe, because some amount of discard is always going to happen with regular sourdough feeding and baking. Instead of tossing that (even small amount of) discard in the trash or compost, save it in its own jar in the fridge to be used later. You can keep adding to this with each feeding and, when you get enough, use it in a recipe where a strong, active starter, such as you would use in bread baking, is not necessarily needed. You could also use the discard right away in a recipe, making it just after feeding your starter, instead of storing it in the fridge. If storing in the fridge, I like to let the discard warm up to room temperature before using in a recipe. Examples of recipes that are perfect for discard include: waffles, quick breads (such as banana bread or cornbread), cakes and cookies, scones and biscuits, and pancakes, both sweet and savory. I have also heard of folks who use the discard in a batter for deep-frying, but I have not ventured into that wonderland...yet.
With so many different ways to use your leftover starter (and so much time to cook right now), I am hopeful that you are inspired to never toss out perfectly good sourdough starter again. Might I suggest your first discard recipe be pancakes...to inspire you even further, below is my recipe for Sourdough Pancakes that I think you will love.
For the overnight build:
1/2 cup sourdough starter discard--can be active or straight from the fridge
1 cup warm water (about 75 F)
1 1/2 cups flour (can be whole wheat, white, spelt, or a combination of flours)
For the batter:
3 eggs, whisked lightly
1/4 cup milk
4 Tbs melted butter, cooled
1/2 tsp vanilla extract
2 Tbs real maple syrup
1/2 tsp fine sea salt
1/2 tsp baking powder
1/2 tsp baking soda
Pinch of cinnamon
2 tsp apple cider vinegar or lemon juice
Optional add-ins: berries, chopped nuts, bananas, dark chocolate chips
Butter for cooking the pancakes
1. The night before you plan to make pancakes (if making them for breakfast; otherwise, do this 4-8 hours before pancake time):
Stir together the starter, water, and flour in a bowl. Cover with a cloth and let sit on the counter overnight.
2. In the morning, or just prior to making the cakes:
In a large bowl, whisk together the eggs, milk, melted butter, vanilla, and maple syrup. This mixture should look creamy and smooth.
3. Gently fold in the flour/starter mix, being careful not to deflate the air bubbles built up in the overnight fermentation.
4. Sprinkle in the salt, baking powder and soda, and the cinnamon. Gently stir into the batter.
5. Just prior to making the pancakes, stir in the vinegar or lemon juice.
6. Heat a skillet to medium-high heat. Add butter to grease the pan.
7. Using a 1/3 measuring cup, ladle the batter onto the hot pan. Cook on the first side until the pancake is covered in small bubbles, about 2 minutes. (If using add-ins, dot these evenly across the top of the pancake just prior to flipping to the second side.)
8. Flip the pancake and cook another minute or so, until the middle is cooked through but not overcooked or burnt.
9. Remove from the pan and keep warm until serving. Continue with the rest of the batter until all of it is used.
10. Serve with plenty of butter and maple syrup, of course, or your favorite pancake fixings.
**Feel free to double or triple this recipe to serve a bigger crowd or to freeze and serve anytime you get the hankering for a pancake. Simply heat up in a skillet for a few minutes before serving and you are good to go.
