Heat your oven to 425°F and line a baking sheet with parchment paper.

In a medium bowl, whisk together the flour, sugar, salt and baking powder until well combined. Grate the cold butter into the mixture and lightly mix until the butter pieces are coated with flour. Gently toss in the blueberries.

In a separate bowl, whisk together the eggs, sourdough discard, heavy cream, milk, vanilla extract and fresh lemon zest until smooth.

Pour the wet ingredients into the flour mixture and stir gently with a fork just until everything comes together. Work quickly to avoid bursting too many blueberries. If needed, add a teaspoon of cream at a time to incorporate any dry flour.

Turn the dough out onto a lightly floured parchment paper. Gently pat it into a circle about 8-10 inches round and 1 inch thick. Using a sharp knife or bench scraper, cut the dough into 8 triangular wedges.

Transfer the parchment with the scones to a baking sheet. Separate the wedges slightly and bake for about 15 minutes until the edges are golden brown.

While the scones bake, make the glaze by whisking together powdered sugar, heavy cream, lemon juice, lemon zest and a pinch of salt until smooth. Adjust consistency by adding more cream if needed.

Let the scones cool for about 5 minutes after baking, then drizzle with the lemon glaze. Serve warm or at room temperature.
