Sour Cream And 7-up Biscuits

Mix the sour cream into the biscuit mix, using a pastry blender or two
table knives, until mixture is crumbly. Add 7-Up all at once, stir quickly
with a large fork. Turn out onto lightly floured board and quickly knead
6-8 times. Don't overmix or biscuits will be tough. Pat into a square and
cut into about 18 equal pieces using a knife dipped in flour. Can also use
a 2 to 3 inch biscuit cutter. Preheat oven to 400 degrees and cook
biscuits for about 7 minutes.
