Preheat oven to 400 degrees. Prepare 12 muffin cups by greasing or using paper liners.
Sift together flour, sugar, baking powder, and salt.
In a different bowl combine shortening, egg, and milk.
Add wet ingredients to dry ingredients. Carefully fold in blueberries. Don't worry if you crush a couple, the juices make a nice color swirl.
Fill prepared muffin cups 2/3 full.
Bake at 400 degrees for 20-25 minutes until lightly golden.
