Quick Answer
Soda biscuits are a decent option for off-grid cooking, but their shelf life is relatively short compared to other dry goods. They can last for several weeks when stored properly, but their nutritional value will decrease over time. For a more viable option, consider using a mix that includes baking powder instead.
Choosing the Right Flour
When selecting a flour for making soda biscuits, choose a type that has a lower protein content, such as all-purpose flour with a protein level of 10-12%. This will help the biscuits to be more tender. However, keep in mind that lower protein content may result in a less durable biscuit, which may not be suitable for long-term storage.
Mixing and Baking Techniques
To make soda biscuits, mix together 2 cups of flour, 4 teaspoons of baking soda, 1 teaspoon of salt, and 1/4 cup of lard or shortening. Add 3/4 cup of buttermilk and mix the dough until it is just combined. Roll out the dough to a thickness of about 1 inch and use a biscuit cutter to cut out the biscuits. Bake at 425°F (220°C) for 12-15 minutes, or until the biscuits are golden brown.
Storage and Shelf Life
For optimal storage, keep soda biscuits in an airtight container at room temperature. If you live in a hot climate, consider storing the biscuits in the refrigerator to slow down the staling process. Generally, soda biscuits will last for 2-4 weeks when stored properly, but their nutritional value will decrease over time.
