Sourdough Soda Crackers

If you happen to make sourdough bread, you might find yourself in the enviable position of having an excess of starter. Recipes for sourdough always suggest you discard half of it, but that seems an extreme measure. I have managed to add it to all sorts of baking which, while allowing me to use up the excess,  does not make it a real sourdough recipe. So I was very pleased to find a great recipe for banana sourdough pancakes from Justyna at Garlic Matters. These are so simple to make, and the sourdough combined with the baking soda make the lightest and tastiest pancakes I have every had.

Of course, one good recipe often leads to another. As I was thinking of how to use even more of my sourdough, I decided to try this soda trick to make crackers. I have been trying to come up with a fool-proof recipe for a simple cracker, and as luck would have it, I finally succeeded with this one. Light, crispy and good for at least a week in a closed container, they are the perfect snack to have on hand. For my first attempt, I used plain salt on half of them and some za’atar for the other half since I was processing sumac at the time. I expect every time I make these, they will undergo some change of flavour depending on my mood.

Ingredients

1/4 cup water

1 tsp. baking soda

1 tsp. salt

1 cup sourdough starter

enough flour to make a workable dough, about 2 cups

salt, herbs, seeds or other topping (optional)

Method

Dissolve the salt and baking soda in the water. Add to the sourdough and mix thoroughly. Use a large bowl, because the mixture will bubble up and almost double in volume. Gradually mix in enough flour to make a workable dough and knead it until all the flour is incorporated. Divide the dough in half and roll each half to about 1/8th of an inch thickness. I found a pasta maker at the widest setting worked well for this. If using any seasoning or salt, sprinkle it evenly over the surface, then roll it lightly again to keep it from falling off. Puncture the surface with a fork. Cut the crackers in whatever shape and size you want and place on a parchment lined baking tray. Bake at 425 F for 8-10 minutes, or  until the edges turn a golden brown. Makes about 6 dozen 1 inch square crackers.

Needless to say, there is no need to stick to this recipe. I repeated this same process using rye flour instead of wheat, added 1 Tbsp of dark molasses to the water and soda mixture, and sprinkled liberally with caraway seeds before baking. The next one might be cornmeal! So now my problem with excess sourdough starter is solved, and I am now faced with the problem of not having quite enough!
