I found this recipe on bakingbites.com. I didn't have real lemons, so I used lemon juice and omitted the zest. They turned out so good. I would rate them an 8.
Lemon Blueberry Scones
2 cups all purpose flour
1/4 cup sugar
2 tsp baking powder
1/4 tsp salt
6 tbsp butter, chilled
1/2 cup milk
1/4 cup fresh lemon juice
1 tbsp lemon zest
1 cup frozen blueberries
Preheat oven to 400F. Line a baking sheet with parchment paper.
In a large bowl, whisk together flour, sugar, baking powder and salt. Cut butter into 6-8 chunks and add to flour mixture, tossing to coat. Using your fingertips, rub the butter into the flour until mixture is sandy and butter is well distributed, with no pieces larger than a big pea.
Add in milk, lemon juice and lemon zest and stir until dough comes together. If dough is too wet, add an additional tablespoon of flour to the dough.
Either keeping the dough in your mixing bowl, or turning it out onto a lightly floured surface, knead dough for about 1 minute. Flatten dough and add blueberries. Knead gently for 30-60 seconds to distribute them. Divide dough into two balls and press each into a disc about 3/4-inch thick. Use a knife to divide each disc into quarters and place scones on prepared baking sheet.
Bake for 17-22 minutes, until scones are golden brown.
Lemon Glaze (optional)
1 tbsp lemon juice
1/2 cup confectioners’ sugar
Whisk glaze ingredients together until smooth, then drizzle over still-warm scones before serving
