This is one of those recipes that has circulated all over the Internet and Pinterest and I get asked for it a lot, so I thought I would make these and post them. This recipe does produce a really fluffy and light biscuit due to the addition of the soda. They also have just a hint of sweetness. If you do not have good luck with making homemade biscuits, this is a good recipe to use, because I don't think you can mess it up.
As with all of the Pinterest type recipes, I have to experiment and see if they really work. This one works, but I did adjust just a bit for best results. Here is what you will need:
2 1/4 cups baking mix (like Bisquick o Jiffy)
1/2 cup sour cream
2/3 cup 7-Up or any clear carbonated soda will work
1/4 cup butter
Preheat oven to 425 degrees.
Place the butter in a 9"x9" baking pan and place it in the oven to melt the butter. Watch it carefully or it will burn.
Place the baking mix in a mixing bowl. With a pastry cutter or fork, cut the sour cream into the baking mix. Pour in the 7-Up and mix. This makes a very soft dough.
Sprinkle a board or sheet of wax paper with more baking mix and then turn your dough out onto it. Knead and work the dough until it is covered with baking mix. Do Not over work the dough. This is why biscuits turn out sort of tough and not flaky. Just knead enough that you can roll the dough out to cut it.
I use a baking mix that I get at GFS (Gordon Food Services) and it is so much better than any I have ever tried. It has little bits of butter in it. If you have a GFS in your area, check it out. I think they are mostly in the southeast.
Roll it out, leaving it fairly thick for thicker biscuits. Cut with a biscuit cutter or glass or whatever you have. You should get about 9-10 biscuits out of this.
Place each biscuit in the pan, turning them over in the melted butter so that each side gets buttered. Place in a preheated 425 degree oven for 15 minutes or until browned on top!
Serve hot out of oven! They are delicious!
