A recipe from a web site called "Diana's Kitchen", for
Alaska sourdough starter:
1 package Yeast
1 tablespoon Vinegar
2 1/4 cups Warm water
1 teaspoon Salt
2 tablespoons Sugar
2 cups Bread flour
Dissolve yeast in 1/4 cup warm water. Add sugar, vinegar, salt, all purpose flour. Add remaining water until a creamy batter is formed. Place in a glass bowl,cover and let sit until it starts to ferment. About 3 days. It will take on a powerful boozy smell. Stir again until creamy and measure out what is called for in the recipe.
Replenish starter with equal amounts of flour and water.
Store in the fridge and bring to room temp before using. All right, let's get one thing straight, shall we? The yeast you buy at the supermarket is tamed, domesticated yeast. It's been raised, fed, and bred by humans to behave perfectly normally in laboratory conditions for decades. It's an organism called
Saccharomyces cerevisiae and the strains that get made into active dry yeast or any other form of yeast available in the store are genetically tailored through ages of breeding to produce reliable, replicable, swift (comparatively, anyway) results.
Sourdough is produced by wild yeast organisms acting in conjunction with strains of lactobacilli. Depending on where you get your starter, you could have one of several different species, but the most commonly found is
Saccharomyces exiges. It's very very happy to live in acidic conditions, which domesticated yeast is not.
Adding
vinegar to your damned
domestic yeast does NOT magically turn it into a sourdough culture! If you want a sourdough culture, either buy a dried sample of it from the region whose taste you wish to replicate (the local lactobacilli and yeasts vary a great deal) or set out your water and flour and sugar mixture and wait for the local organisms to get down and get frothy with it! Yes, it could take a day or two to see anything happen - deal with it. Sourdough isn't the same as modern yeast. Takes forever, makes a different texture of bread. You can't just whip up sourdough, you can't even do sourdough in the space of four hours. You have to invest time in it. Either be content with your packets of
S. cerevisiae or set aside a chunk of time for the wild stuff. Don't try to pretend one is the same as the other.
... okay, I feel better now.
