What each ingredient does
- Flour
- Provides the structure that holds the biscuits together as they bake.
- Shortening
- Adds fat that keeps the biscuits tender and helps them separate into flaky layers.
- Sour cream
- Adds moisture and acidity that tenderize the dough and react with leaveners for lift.
- Baking powder
- Releases gas in the oven, causing the biscuits to rise and become light.
- Baking soda
- Reacts with the sour cream's acidity to produce gas, adding extra rise and browning.
The step that matters
Work in the shortening and sour cream until combined. Overworking the dough develops gluten, making biscuits tough. Mixing only until combined keeps the fat in small pieces, which creates flaky layers and a tender crumb.
