The "Biscuit Grind" (5 Mins)
Preheat oven to 400°F (200°C). In a large bowl, whisk flour, sugar, baking powder, baking soda, and salt. Add the COLD cubed butter. Use a pastry cutter or your fingers to smash the butter into the flour until it looks like coarse crumbs (this creates flaky layers, just like a biscuit). 2. The Liquid Mix (2 Mins)
Make a well in the center. Pour in the Sourdough Discard and milk. Stir gently until just combined. Do not overmix! If you overwork this dough, it will be tough, not fluffy. It should look shaggy. 3. Roll & Fill (8 Mins)
Dump the dough onto a floured counter. Knead it gently 3-4 times just to bring it together. Roll it into a 12x15 inch rectangle. Smear the softened butter all over. Sprinkle the brown sugar/cinnamon mix edge-to-edge. 4. Cut & Pack (5 Mins)
Roll it up tight into a log. Cut into 12 even rolls (Use dental floss for a clean cut!). Place them in a greased 9x13 pan. They can touch slightly, but give them room to expand. 5. (Crucial Step!)
Pour the Heavy Cream into the gaps between the rolls. You don't need to garnish the tops, just fill the spaces. Pro Tip: Warm the cream in the microwave for 30 seconds first. If you pour ice-cold cream onto the dough, it can shock the oven temperature and hinder the rise. This cream will thicken into a caramel sauce and steam the dough. 6. Bake & Glaze
Bake for 20-25 minutes until golden brown. While hot, whisk the Glaze ingredients together until smooth and slather over the warm rolls.
