Marilyn: This is how the recipe was written down. This is how I make it in my blender:
Add the buttermilk & eggs to the blender. While the blender is mixing these 2 ingredients, I add the oil & all other ingredients except for the flour, which I add last. I find that I have to add more flour than the recipe calls for [I think because buttermilk has gotten thinner over the years!]. I usually add at least a couple of heaping tablespoons or enough to make the pancakes keep their shape in the skillet. I occasionally have made this recipe substituting 2 C. of yogurt (whatever I have in the refrigerator) in place of the buttermilk, but it's not as good. I also sometimes sprinkle in some wheat germ. Mom often made strawberry-rhubarb sauce to put on the pancakes. Mmmmmm! And on occasion (way back when), whipped cream & lingonberries.
