A few tips I learned about making great biscuits:
- Buy the expensive buttermilk; it makes a big difference
- Don't use self-rising flour as your bench flour; it makes for bitter biscuits
- Don't twist the cookie cutter as you press down to cut out biscuits; the biscuit will not rise as well.
- Use fresh baking soda.
- Don't over handle the dough. Mix until just combined and cutout/drop into the pan.
