Citric acid can be used to replace liquid lemon juice or vinegar in recipes to add a sourness. It can easily mix into liquids and will decompose when heated above 174 Celsius or 345.2 Fahrenheit. It can enhance the flavor in a citrus-based recipe.
A few shakes of the "sour salt" adds a strong flavor to frostings or glazes. Another popular application is adding it to sourdough or rye breads for a touch of tang. Bread products usually only need a teaspoon or less.
Store it in a dry, cool place without exposure to moisture.
