I've made pancakes once a week for 20+ years using this recipe from a 30-year-old Betty Crocker cookbook (which I did not have to look up!):
1 cup flour
1 egg
3/4 cup milk
tablespoon baking powder
tablespoon sugar
2 tablespoons vegetable oil
dash of salt
I double or triple this depending on how many people are eating and whether it's breakfast, brunch or supper.
I wisk the egg, then add the milk and oil. Then I throw in the rest of the stuff. I know you're supposed to mix it up, sift, etc., but I never do! Oil the skillet (Silverstone-type is best) and reoil it during cooking if the pancakes start sticking.
I get the skillet temp right by making tiny test cakes -- kids love them.
I have a waffle recipe -- has baking soda and lots of margarine, but I don't know it by heart like the pancake one.
