1. Prepare for Baking: Setting the Stage for Success

1. Preheat Oven: Preheat your oven to 450°F (232°C).
2. Line Baking Sheet: Line a large baking sheet with parchment paper.

2. Combine Dry Ingredients: Ensuring Even Distribution

1. Whisk Together: In a large bowl, whisk together the flour, salt, sugar, and baking powder until well combined.

3. Add Wet Ingredients and Blueberries: Bringing the Dough Together

1. Pour in Milk: Make a well in the center of the dry ingredients and pour in the cold milk and add the blueberries.
2. Stir Gently: Stir gently until just combined. Be careful not to overmix. The dough will be slightly sticky.

4. Incorporate Frozen Butter: A Key Step for Flakiness

1. Freeze Butter: Prior to baking, place one stick of butter (1/2 cup) in the freezer for about an hour.
2. Remove and Break: Remove the frozen butter from the freezer and break it into chunks.
   • Tip: You can also grate the frozen butter using a box grater.
3. Spread Over Dough: Spread the frozen butter chunks evenly over the biscuit dough.

5. Kneading and Folding: Creating Layers of Flavor

1. Fold and Knead: Gently fold the blueberry biscuit dough and knead until the frozen butter chunks are evenly distributed throughout the dough. This process helps create flaky layers in the biscuits.
   • Tip: Work quickly so the butter doesn’t melt too much.

6. Rolling and Cutting: Shaping the Biscuits

1. Roll Out Dough: Turn the dough out onto a lightly floured surface. Gently roll out the dough to a thickness of about ¼ to ⅛ inch.
2. Cut Biscuits: Use a biscuit cutter (or a sharp knife) to cut out approximately 6 biscuits from the rolled-out dough.
   • Tip: Dip the biscuit cutter in flour before each cut to prevent sticking.

7. Bake the Biscuits: Achieving Golden-Brown Perfection

1. Place on Baking Sheet: Place the cut biscuits on the prepared baking sheet, leaving a little space between each one.
2. Bake: Bake for 7 to 12 minutes, or until the biscuits are golden brown on top.

8. Prepare the Glaze: A Sweet and Tangy Finish

1. Melt Butter: While the biscuits are baking, melt 1 tablespoon of butter.
2. Brush Biscuits: Gently brush the tops of the hot biscuits with the melted butter.
3. Combine Glaze Ingredients: In a small bowl, whisk together the powdered sugar, water, vanilla extract, and lemon juice until smooth.
   • Tip: Adjust the consistency of the glaze by adding more water (to thin) or more powdered sugar (to thicken) as needed.
4. Drizzle: Drizzle the glaze over the warm biscuits.

9. Cool and Serve: Enjoying Your Sweet Blueberry Biscuits

1. Cool Slightly: Let the biscuits cool slightly on the baking sheet for a few minutes before transferring them to a wire rack or serving plate.
2. Serve Warm: These biscuits are best enjoyed warm, when the glaze is still slightly soft.
