Blueberry Cake

Here is a recipe from my mom's grandmother's Grange Cookbook.

Blueberry Cake

Cream:
1/c shortening (I use butter)
1 egg
1 c sugar
1 t vanilla

Add 1 c sour milk (I like to sour it with lemon juice, but you can use vinegar)
Stir in:
1 t baking soda
2 c flour
1/2 t salt
1 1/2 c blueberries (also good with blackberries)

Sprinkle top with cinnamon and sugar

Bake at 350 for 30 min. in a 9x 11 pan.

I always double the recipe and make in my BIG glass pan...I think it is 10x13. Check with inserting knife.
