Notes
*This recipe was written using an average of the dip and sweep method for measuring flour and the spoon and level method. If you are using a scale, you will need to add 3/4 oz or 22 gto the measurement for each cup of flour.Substitutions:
You can use frozen blueberries for this recipe.
Instead of sparkling sugar, you can drizzle these scones with a vanilla icing after baking!
Expert Tips:
10 Tablespoons of vegetable shortening is equal to 1/2 cup + 2 Tablespoons.
If you don't have a pastry blender, you can use a fork to cut in the vegetable shortening!
Be careful to not over-mix the dough.
Remember to dry your blueberries! If you add them while they're still wet, it will make the dough very sticky and hard to work with.
Do not place more than 6 scones per pan! They tend to spread.
Brushing with milk and topping with sparkling sugar is optional, but highly recommended!
Every oven bakes differently. Keep an eye on the scones!
