DIY Biscuit Mix

So awhile ago I inherited a treasure trove of recipes from my grandmother. It included a lot of things that can be made with Bisquick. A lot of them looked like they could be pretty fun to experiment with, but first I had to come up with my own baking mix. This is a modification of my own buttermilk biscuit recipe and, while it does need to be refrigerated, it can keep for two months if sealed and even longer in the freezer.

Ingredients:

500 gr AP flour
2 tbsp baking powder
½ tsp baking soda
1 tsp salt
½ c buttermilk powder
½ c shortening, butter, or lard chilled and cut into cubes

Directions:

In a food processor combine the flour, baking powder, baking soda, salt, and buttermilk powder.
Pulse a few times to make sure everything is combined.
Add your choice of fat, one cube at a time, and pulse until incorporated before adding the next one.
Store in an airtight container in the fridge for up to two months.
