This is a basic muffin recipe a bit different from those posted in that instead of oil it uses butter. The variations that can be used are in the directions listed and not in the ingredients list as that would be too difficult to decipher. I found this in the FIRST Magazine I believe in 1989. Some tips to great muffin making...DO NOT overstir the batter - just mix until combined - it may still be a little lumpy. It is okay to fill your muffin cups to near the top - this will give you a high crown on your muffins. A nice tip I read too was to make sure to grease or spray the "TOP" of the muffin pan - that way any muffin that comes in contact with it while baking will not stick to muffin pan and will allow it to keep rising and spreading out.
