In a large mixing bowl combine the flour, baking powder, and salt. Stir. Grate your butter and add it to the dry ingredients.
Work the butter into the flour until they are pea sized. If you grate the butter it is much easier to do and takes little time.
Stir in the chives and grated cheese into the flour mixture.
Add the sourdough discard and half of the milk. Use a fork to fold it all together. Continue to add a small amount of milk until it is a shaggy dough. You want it to hold together when you press it together.
Take the dough out onto a lightly floured surface and shape it into a rectangle. Push it together so that all the dough stays together. You can use a bench scraper for this to make it more manageable.
Fold the top third of the dough over to the center and the bottom third of the dough over the top of that and reshape it. Like you are folding a piece of paper.
Shape the dough into another rectangle and repeat the folding process one more time.
Shape it again into a rectangle and then cut the dough. with a knife into squares or triangles. Whatever shape you prefer your scones to be.
Place them on a baking sheet (you can line. it with parchment paper or a silicone baking sheet and put them in the fridge for 30 minutes to 1 hour. You can also put them in the freezer to make them cool off faster.
Pre-heat your oven to 425 degrees F.
Remove the scones from the fridge and brush them with milk and some grated cheese.
PLace in the oven and bake for 15-20 minutes
Once they are baked golden brown, bring them out of the oven and brush them with the garlic butter sauce.
Let them cool for about 10 minutes and then enjoy!
You can store these in an airtight container for 2-3 days. They are best served warm
