The best 7-Up biscuits

Today I made tonkatsu with mixed veg and 7-Up biscuits. These are just the best things to make if you need something to go as a side carb. Here's the recipe:

2 cups Bisquick*
1/2 cup sour cream
1/2 cup 7-up
1/4 cup melted butter

Preheat oven to 450F (220C)
Cut sour cream into biscuit mix, add 7-Up and butter. Makes a very soft dough.
Sprinkle additional biscuit mix on board or table and pat dough out. Makes about nine 3/4" high biscuits.  Place cut biscuits in pan and bake for 12-15 minutes or until golden brown.
