My aunt who was about 100 years old made rolls so sweet and light they almost floated off the plate, I could never duplicate them in 40 years.
There are numerous recipes (basically all the same!) online for simple light delicious rolls made with flour and 7-Up. Google 7-Up Biscuits, you won’t be sorry! Bisquik, sour cream, 7-up, and melted butter, dee-licious.
