Homemade Blueberry Muffins

2 cups flour
1 cup white sugar
3/4 cup butter

Sift & blend as for pastry (I just use 2 knives to cut the butter into the flour/sugar). Reserve 1/2 cup of it for topping.

In a separate bowl mix the following together and then add to above ingredients.

1 cup sour milk (milk + 1 tbsp vinegar) or buttermilk
1 tsp baking soda
1 egg

Mix the two together and blend only until moist (the batter may still be lumpy). Fold in 1/2 cup frozen blueberries (I do a little more).

Spoon into muffin cups 3/4 full & sprinkle the reserved topping on top.

Bake 350 for 15-20 minutes. Yields 12-15 muffins.
