Start by mixing flour, baking powder, baking soda, salt, and pepper in a large bowl. I like to whisk everything well so the leavening agents distribute evenly. This step ensures consistent texture in every bite.
Add cold, cubed butter into the flour mixture and rub it in using your fingers or a pastry cutter. The mixture should resemble coarse crumbs with small butter pieces. This is what gives the scones their flaky texture.
Now fold in the crumbled goat’s cheese, chopped dill, and finely chopped onion. Make sure everything is evenly distributed without overmixing. This step builds the signature savory flavor of the scones.
In a separate bowl, whisk together buttermilk and egg. Slowly pour this into the dry mixture while gently stirring. Mix just until the dough comes together—overmixing will make the scones dense.
Turn the dough onto a lightly floured surface and gently knead it a few times. Pat it into a round about 1-inch thick, then cut into wedges or use a cutter. Keep the dough soft and slightly sticky for best results.
Place the scones on a lined baking tray and brush the tops with milk. Bake in a preheated oven at 200°C (400°F) for about 18–22 minutes until golden brown. Let them cool slightly before serving.
