Mix the dough: Use a cheese grater to grate the cold butter into a mixing bowl. Add the flour and use a bench scraper or pastry cutter to cut the butter into the flour. Add the sourdough starter discard, buttermilk, honey and salt. Mix with a spatula until the ingredients are well incorporated. Cover the bowl and let rest on the counter for 10-12 hours. (DO NOT add the baking soda or baking powder. This will be added right before rolling out the dough)
Make cinnamon sugar filling and glaze: Mix the brown sugar and cinnamon in a small bowl, set aside. In a separate bowl, mix the glaze ingredients and set aside. Preheat oven to 375°F (190°C) and butter a 12" cast iron skillet.
Shape the rolls and place them in a round disposable tin lined with parchment paper. Cover with plastic wrap and then tightly with foil before freezing for up to 3 months. When you're ready to bake, preheat the oven to 350°F (176°C). Uncover the rolls and bake them for 40-45 minutes, or until the tops are golden brown.
