Preheat the Oven: Set your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Prepare Dry Ingredients: In a large mixing bowl, use a pastry cutter or your fingers to mix the cold butter and flour until the mixture resembles coarse crumbs. Stir in salt, baking powder, Chinese sausage and chopped scallions.
Combine Wet Ingredients: Add milk and stir until just combined.
Shape the Dough: Transfer the dough onto a floured surface and knead gently a few times. Pat into a 1-inch thick round and cut into wedges or rounds.
Brush and Bake: Place scones on the baking sheet, brush with egg wash or cream, and sprinkle with sesame seeds if using. Bake for 15-18 minutes until golden brown.
Cool and Serve: Let cool slightly before serving. Enjoy warm with miso butter or a savory spread.
