Mix 1/4 cup warm water with 1 package yeast + 1 tsp sugar + 1 tsp flour in a small bowl. Let sit until yeast is bubbly.
In a stand mixer or large bowl, combine:
1 stick butter (softened)
1 cup sour cream
2/3 cup heavy cream
3 eggs
1 tbsp salt
1/4 cup sugar
1 cup water
About 5 cups bread flour
Mix until well combined, and continue mixing (or knead by hand), and adding additional flour until you have a smooth, stretchy, and slightly sticky dough.
In the large mixing bowl, cover the dough and let rest in a warm spot until roughly doubled in size.
Melt remaining stick of butter
Turn out dough onto a floured surface and divide into two halves. (Proceed with next steps for each half)
Roll out into a rectangle until roughly 1/2 inch thick.
Brush entire surface with melted butter
With a bench scraper or knife, cut dough into long triangles (split rectangle in half the long way first for smaller rolls).
Grab each segment by the short end, and flip/fling the long end around to roll up (butter side IN)
Place roughly 1.5 inches apart on a baking sheet
Repeat process with the other half of dough
Cover rolls with a flour sack towel, and let rise until roughly doubled in size. Also, turn on oven to 350°
Bake at 350° degrees (Fahrenheit) for 20 minutes or until lightly golden brown
