There are 3 keys to baking really good Savory Scones: 1. Use cold ingredients. No room temperature butter or milk, bring them out from the fridge just when you need them. 2. Don't overmix. Mix until combined, but not more. It's fine if there are patches with more flour or butter, the dough just needs to be somewhat cohesive. 3. Keep the heat high. Make sure you're oven is preheated and bake at 435°F (225°C).
