Makes 6 biscuits
Adapted from Come On In: Recipes from the Junior League of Jackson, Mississippi
2 cups flour
Preheat oven to 400 F.
In a large bowl combine flour, baking powder, baking soda, salt & sugar and blend. Using your hands, mix in shortening until mixture resembles a coarse meal (this can also be done quickly in a food processor). Whisk together the egg & buttermilk and stir into flour mixture until combined. Mix in blueberries.
Dump dough out onto a floured surface and pat into a rough rectangle about an inch thick. Cut dough using a 3 inch biscuit cutter (a glass works too) & place on a parchment lined baking sheet. Bake for 15 minutes until tops are pale golden.
While the biscuits are baking, prepare the lemon glaze by mixing together the lemon zest, lemon juice, butter, confectioners sugar & vanilla in a small bowl. Mix until smooth. Spoon glaze over warm biscuits and serve.These will keep for a day covered at room temperature but are best served the day they're made.
