Preheat oven to 400° F. In a food processor, combine flour, sliced cold butter, garlic salt, baking soda, and baking powder. Pulse until it forms a nice crumble. Chop your bacon, scallions, and jalapeno (remember to save some slices for the top of your scones). Grate your cheese and set aside 1/2 cup for the top of your scones. To your flour mixture in the food processor, add buttermilk, chopped ingredients, and cheese. Pulse a few times until combined (don't over mix!). Pour out on a flat surface and form a rectangle. Cut dough into desired triangles. Cover a baking sheet with parchment paper. Place dough triangles on baking sheet. Sprinkle with saved cheddar and slices of jalapeno. Bake in oven on middle rack for 22-25 minutes until golden grown on top. Remove from oven and serve immediately or save for later! Good hot or cold! Freeze well too! Enjoy!
