Platinum Instant Sourdough adds a real sourdough culture – and real sourdough flavor – to any of your favorite yeast bread recipes.
When used in place of a standard packet of yeast in any of your favorite yeast recipes, Platinum Instant Sourdough adds sourdough flavor to the final baked good.
Simply substitute one packet of Platinum Instant Sourdough for one 0.25 oz packet of any dry yeast in any yeast bread recipe.
Follow the recipe instructions or blend Platinum Instant Sourdough with dry ingredients. Add very warm liquid – make sure it’s not too hot to touch. Suggested temperature range: 120° – 130°F.
One packet of Platinum Instant Sourdough will raise up to 4 cups (about 1 pound) of flour.
Since the packet contains a blend of yeast and sourdough starter, only full packets of Platinum Instant Sourdough should be used in recipes.
Platinum Instant Sourdough is NOT intended to be used in place of a sourdough starter in a traditional sourdough recipe that calls for a sourdough starter. Use it to replace active dry or instant yeast in a recipe.
Be good to your yeast, and it will perform well in your bread! Don’t forget that yeast is a living organism, and its freshness and shelf life are dependent on how the yeast is stored. Dry yeast will lose its leavening power if exposed to air, moisture or heat, even when it is still in a sealed jar or package. Learning the correct way to store your yeast will keep it fresher longer.
