Cover a baking sheet with parchment paper.
In a large bowl, whisk together the flour, baking powder, sugar, and salt until very fluffy, lump-free, and fully combined. Zest the lemon and whisk the zest it into the flour mixture.
Drizzle the olive oil over the flour mixture and, using a fork, mix to combine so the mixture looks crumbly.
Whisk the egg in a liquid measuring cup. Squeeze in ¼ cup of lemon juice from the lemon and add the milk, then mix to combine. Pour the liquid over the flour mixture and sprinkle with the cherries. Using the fork, mix the ingredients until they just come together to form a sticky dough.
Turn the dough onto a lightly floured surface and form it into a disk approximately 1 inch thick and 8 inches in diameter. Using a biscuit cutter or a floured glass, cut into rounds, and place on a prepared baking pan. Gently reroll any scraps to cut out the remaining dough.
Preheat the oven to 400°F and place the scones in the freezer to chill slightly while the oven preheats. Place the baking sheet in the preheated oven and bake for 10 minutes, until golden and puffed.
Remove from oven and transfer to a cooling rack or serving platter. Serve warm with a fresh cup of tea.
