In a large bowl, gently whisk together the active sourdough starter, warm milk, warm water, and sugar until well combined.
Gradually add the all-purpose flour and salt to the wet mixture, stirring until just combined. Avoid overmixing; a few lumps are acceptable.
Cover the bowl with a clean kitchen towel or plastic wrap and let it rest at room temperature for 1 to 2 hours. The mixture should become slightly bubbly and expand.
In a small bowl, dissolve the baking soda in 1 tablespoon of warm water. Add this mixture to the crumpet batter and stir gently to incorporate. This step creates the characteristic crumpet holes.
Heat a non-stick pan or griddle over medium-low heat. Lightly grease crumpet rings (approximately 3.5 inches / 9 cm in diameter) and place them in the hot pan.
Pour about 1/4 to 1/3 cup of batter into each crumpet ring, filling it about halfway. Cook for 5-7 minutes, or until the top is set and covered in small bubbles, and the edges are dry.
Carefully remove the crumpet rings. Flip the crumpets and cook for another 2-3 minutes on the other side until lightly golden.
Transfer the cooked crumpets to a wire rack to cool slightly. Serve warm with your favorite toppings like butter, jam, or honey.
